Project X IO Iron Shafts

I was on the Project X website the other day, and I saw they have a new(ish) offering called Project X IO iron shaft.  There is another iron shaft called the "Project X LS", but I think that won't work for me.  The IO seems a little more in line with my swing (98-101 mph driver swing speed depending on time of day and weather, 7i swing speed = 79 mph, tend to have lower spin #'s off the mid irons, but decent spin with the short irons/wedges irons with the LZ 6.0 shafts in my JPX-900s).  What intrigued me was that the IO (Individually Optimized) was engineered to modify the profile for each different weight.  From an aesthetics standpoint, I really like the brushed chrome finish to it!!  

Has anyone tested this Project X IO shaft out yet - if so, can you give some feedback?  Thanks!

I recently tried the shafts in a demo. I currently play Callaway Apex CF16's with Project X 6.0 shafts. I was trying out the Apex 21's. With the same Project X shafts I got similar results to my current clubs. With the IO my dispersion was much tighter, both side to side and front to back. Spin numbers were much more consistent with the IO for me.

I had a iron fitting on 7/20. I tried lots of shafts and heads. For me, the Project X IO 5.5 was the clear winner. I was swinging the 7 irons at 85-90 mph. I just hit them better. You could fee the load but they still felt firm. I paired them with TaylorMade P7MB blades to replace my old '84 Hogan Apex PCs. The IO shafts had a similar feel to the Apex #4 Stiff shafts in my Hogans.

I think it's almost like an update to the PX Flighted. I've hit them in the new Apex MB and they feel great, a bit lighter than standard PX but I was still getting really nice consistency with them. I would think most would prefer the feel over the standard PX as well.

Ended up getting the Apex 21's with Project X IO 6.0 shafts. They feel sooo much nicer than my previous clubs. Not sure how much is the head vs shaft but I love this combo. Shots just feel pure.
