Guys I'm thinking about getting either a new CSZT or picking up a used CS in the classifieds. Is there that much of a difference with the zero torque system vs the roller guard system.
This is true. I find the z5 to be smoother then the turbo cam. Eith the right tune u can get the 14 with z5 cam around 348 ibo. So not much gain in speed for the 15.Id get the new one. Can shoot less poundage and still get the same speed. Sounds like a win to me.
