I have a SP2REVO2 Revo and tried the shaft on my Predator 8K04. They play the same in my opinion, so I know it works. Also tried it on other sticks with the same Uni-Lok joints and they all play good. So the shaft is what is good on the stick. I love my Revo Shaft and will never go back to Wood shafts form my every day player. These shafts are very dent and nick resistant. Very slick shafts, if it starts to get sticky, I just clean it with those cheap glass towelettes from Walmart. Mine has the standard soft Predator tip on it and it plays ok. As soon as this tip wears out I will be going to my favorite tip which is the Kamikazee Med.
I think they will sell at the expo for around $500 which is cheap in my opinion for a rugged, slick, no-deflection shaft that should last you a lifetime.
