I haven't tried the classic pro, but I got the regular classic a week ago and I find that it is much more stiff than predators. I used to shoot with a 314 2, and have tried the 314, Z2 and OB-1 and the classic is very stiff compared to the others. Almost feels like my schon shaft. On a stiffness spectrum it goes from OB-1, predator 314, predator z, and then OB classic. There is more deflection with it though. Not terribly a lot, but noticeably more than with the predators. I still love it so far though. It's like the best of both worlds - the stiffness that I want but with the lower deflection quality. It's very accurate, hits like a dream. I can put a crap ton of spin on the ball and park it wherever I want. Breaks like a hammer too. Seamless fit onto my schon. I highly recommend it, especially since predator doesn't cover warping in their warranty but OB does. I'm definitely on the OB bandwagon now. Great product and great company.
