I have played many Ozik shafts in the past and hit them side by side with other high end shafts like Diamana Red/Blue/White, AXIV, GD YS-6/7, Fujikura 660/652/757. Thsy aren't bad shafts, but for me, other shafts fit me better.
I hit the Altus and Blueboard side-by-side in identical Ping Rapture heads on a launch monitor and I launched the Blueboard higher than the Altus. It had lower spin but NOT higher launch, so be careful before you buy into all the Altus hype.
I also tried the Code-8 in my fairway woods. Very good shaft, but again when hitting side-by-side with the Blueboard 93, I got better results with the BB.
Finally I had the Altus hybrid in my Adams hybrid. Again a good shaft, but when compared to a Fujikura Rombax 8D07HB in the same head, the Fujikura won out.
Matrix shafts are not junk, but they are expensive, so before you go down that road and spend the big bucks get on a launch monitor to know exactly how you are hitting your driver, fairway woods and/or hybrids so you know what you need (if anything).
