Follow up as i am learning about shaft trimming. Are you stating you cut a half inch off the tip end already from the Driver project or was that from the butt end?
I have the GWX on my 3 wood and i do like it just feel like possible tightening the whippyness a little. Same as my driver. As spin rate seems a little too high. Driver around 2800 and 3 wood 3800. 
Also did you decrease the loft on the 3 wood like in the driver or left standard?

Want to provide an update:
Been able to use multiple simulators now. Golfzon, Trackman, Full Swing.
I am a member at a Sim with Full Swing so it is my most used sim (3-5x a week and play in a league). Id say on average my backspin on my driver on Full Swing is around 2500-2600 ball speed around 155-165, with my drive mainly being baby draw to big draws. No really any slices except more pushes/ push fade. Of course had drive that were in the 3000-4000 spin rate. Club head speed here showing 108-115
Trackman I was able to play one session. Mainly getting spin rates around 2600 again but had some drive going 265 carry with 3200 spin rate. Ball speed around 160. Few drive with spin rate around 1800-2200 but those were more low drives.  Club head about the same as Full Swing (108-114). Id say playing mostly a draw but some fades rather than the push on full swing.
Golfzon id say average spin rate was showing around 3000, feel like i couldn't get below 2800 on my drive. I have played this sim about 3 time with the OttoPhlex. Carry mainly going 265-280 on those 3200 spin rate drives. Club head speed id say was about the same and same as ball speed. Just seem to be playing more Fade/slice and small draws. 
 
For reference gaming the GPLB A 45g cut down to 45in playing with a TSi3 set to 9.25 degree D1.5. 
 
Small test of the GPLB GWX in the PING g425 3wood playing at 43in, felt goo just maybe need to cut down and might want it a little stiffer. Only tested on Golfzon but want to test on full swing and trackman as well.

That's good to know. I have a pretty good relationship with the store as I run a Foundation and Golf outing and always go to them for gifts/raffle items. 
When i brought the shaft there to be made i was talking to the club maker about it and he was confused at first with my SS and going to A flex shaft. I told him about "OttoPhlex". When I picked it up he said he put the swing weight to D1 and that he looked up this forum and gave it a read, was curious how it turns out. 

Okay so had my first swings with my GPLB 45 A flex shaft D1 swing weight
Right now distance is a little longer/same as my Oban 04 65gram shaft.  Backspin is a little higher at 2700-2800 rpm, lowest I got was 2500rpm. As with my Oban lowest I get is 2300 RPM. Not sure if the Full Swing simulator reads it a bit higher. 
Yardages are around 275 carry with rollout to 292. 
Swing speeds is 110-115mph as my Oban is usually 108-112. Ball speed was around 155-165mph. 
Still some more testing to do, also need to dial in driver swing. Was thinking on adjust swing weight to either D0 or D1.5 to see a difference either way. 
I do enjoy that fact that I can feel the load better in the GPLB. I feel like in my Oban (not sure since its Pured) I have a hard time feeling it load. Plus when I have a lower SS on some drives like a 105, the GPLB feels better. 

So I order the GPL GWX as I plan to test this out in my 3 wood as well. 
What would you recommend the cut length be for the 3 wood, the same I play it at or a little shorter? 
Also, just a general question/advice. If I want to start working on the shafts myself where should I start to learn what to do?

@qLofty
I just measured and my 3 wood is playing right at 42.5". For reference, I'm 6' 2.5" and with the OP setup this feels very controllable and distance is a non issue. 
On another note, I found the video that inspired my DIY shaft puller and is similar to @Bang60's. This is the best DIY puller I've been able to find so far and works great!

So my driver is TSi3 at 10° at B1 setting. I turned it to C1 setting to get it down to 9.25°. Need to spend some more time with it but do enough the load feel I get with it. 
As for the disbursement and control. It does feel a bit better. I play a draw as I spent so much time fixing over the top when I first started golfing that it takes every fiber in my body to swing out to in now so I always swing in to out. So my misses are big draws/hooks. They did feel tighter and was a point on the range had 4 drives land within 5 yards of each other. Feel like with my Oban I have to been completely on for that to happen. 
Going to be test it more this weekend and might try to test on another simulator to compare the spin rate. Going to try to get a 30 minute session at PGASS.

As for the 3 wood, I believe 43" playing length is about where you wanna start. I'll measure mine as soon as I'm off of work but I think mine might be in the 42.5" range. I believe I cut 1/2" from the tip, installed it, and then measured the playing length to finish the butt end trimming. 

AJ at Mobile Clubmaker Golf (YouTube) has a load of great videos directed specifically to DIY builders. He shows how you can do a lot of basic building with stuff around the house. 
@peakationjust mentioned a few good items. 
Overall, you'll want some decent equipment for the following:
Measuring: weight and length; a good food scale with .00 g, a tape measure, and/or an aluminum yard stick. 
Prepping/cleaning: sandpaper; 220 grit for tip prep, 60 grit for hosel cleaning and tip scoring; Acetone for cleaning and ferrule turning. Rubbing alcohol also for pre glue cleaning. Lint free shop towels. Good paper towels. 
Heat: butane torch for iron shaft removal. Heat gun for graphite shafts removal and grip tape heating/removal. Once you get your heating skills dialed in, you really can do everything with the torch BUT you can ruin a graphite shaft if you aren't careful. 
Cutting: for graphite shafts, a good jigsaw or hacksaw with a fine blade (10+ TPI). 
Miscellaneous items that are extremely helpful:
Table vice + rubber shaft clamp: this almost a must have if you want to go deeper into club building. If you have a Harbor freight in your area, you can get an adequate one for around $30-$40
Dremel (like) tool. Great for cutting, cleaning, grinding, prepping. 
Graphite shaft puller: this and my next recommendation are going to be worth their weight in gold. If you can spare the $100 or so and can buy a legit budget puller from Golfworks, go that route. A nicer puller would run $180+. If you plan to do anything with the tip end of a graphite shaft, this is a MUST. You can also search for DIY shaft puller and go that route too but those also require additional fabrication and ingenuity. 
Air compressor (portable): the disclaimer on this is that you have to be partial to full rubber grips. Winn and some others won't work with this method. I'll never install grips with sticky tape and solvent again. Once you have all of your grips converted to this method, moving forward, you can remove, swap, reuse grips effortlessly. Want to try and extra wrap? 5 seconds and you can remove the grip, add the wrap, and put the grip back on. 
Oh.. and a big roll of wide masking tape for grips.

There are a lot of club building videos on youtube. I cant remember where I started, but I think Hireko has some good ones. You dont need that much equipment either to start with. To properly measure clubs I recommend a club ruler like this: https://www.hirekogolf.com/dynacraft-bench-ruler-soleplate-kit.html. You probably have a digital weight and then you need glue, sand paper and a heat gun (or torch). I have more "things" but that is really all I use regularly.

When cutting down the shaft, do you recommend going from tip or butt end?
I plan on cutting down to 45in as well just curious which end?
Also I have a buddy who is interested but swings around 120mph, do you think the R flex or A Flex would be better starting point?
