So I got my PLB 45 in last week and although I could swear I ordered the A flex, a R flex arrived. I double checked on ebay and what do you know, I had somehow selected the R. I did some work last week to get the swing weight down to the D0-D1 which took a bit of trial and error. Ultimately, I had to remove the slider weight on my Callaway Epic Flash in order to keep the overall weight in a desirable range. (I am about as green as can be when it comes to club building other than changing grips.) I have now ordered some butt end weights to play around with in the future. Unfortunately, we are experiencing a cold snap in Nashville and with other plans in the way I was not able to get to the driving range last week prior to my Saturday tee time. I did set up my net in the back yard and take a few swings with the driver, but that is not the same and even with my swing caddy showing ball speed and carry distance, I don't trust the driver practice unless I can see it fly. My round Saturday being set, I took my gamer shaft as well as the new OP shaft to the range to see if I could justify gaming the new one with little to basically no prior practice session. High Saturday was 39, it was around 34 when I teed off and never really got over 37 the entire round. Weather insight included to basically say this round and first update are an outlier and I will need further testing. I took the swing caddie to the range as well to try to get an idea on distance. It was so cold and I was so bundled up that I was basically hovering in the 107-109 swing speed range. I seriously doubt if I much eclipsed these numbers during the round. I generally liked the ball flight and distance I was seeing on the range enough to just go for it and see what happened during the actual round. Was paired up with 1 other crazy yahoo willing to brave the cold and piped the first drive center cut what I would estimate around a 265 carry. It being so cold, I can't say I would have expected any distance difference with my gamer shaft setup. I felt like overall I did see what some of the other posters noticed with a tighter dispersion throughout the round. I will absolutely need to get some range time in to dial in the tempo feeling and do some numbers comparisons. One note is I do not like the sound of the head with the slider weight removed. I ordered some grip in weight inserts today and hope to maintain the correct swing weight while adding the weight back in the driver head. I do realize this will bring up my overall weight but if I can get back to the sound I am used to, I think the added intrinsic value will be worth it to me. Only testing will tell though! Enjoy this thread, I was telling the guy I was paired with about it and enjoyed watching as the glassiness started taking over his eyes. Not for the faint of heart? More to come. Thanks!
