I am in the market for a new shaft. I own a micky-dermott and im interested in thier i-shafts i took a test on ozonebilliards.com to see which of the three shafts would fit my game. The i-2 shaft seems to be what they recommend for me. My only problem is how do i know until i hit with it? These shafts are upwards of $200.00 and i would like to be able to try it out b4 i put out the money. The predator shaft dissapointed me a long time ago i paid $200.00 for it tried it for a year and just did'nt like it sold it for $50.00. You can get your money back as long as you don't chalk the tip! How the f can i try any spin without chalking the tip? Does anyone know where you can try out shafts b4 you purchase them? Thanks.
