I currently shoot a Switchback xt and am considering going to one of the new High Speed Bows, somewhere in the area of 330 plus. I have no accuracy problems and currently my slick tricks impact right with my field tips. I really like the idea of more speed for the cushion it gives me on longer range shots and yardage estimation. My concern is, when I gain a lot more speed, if my form is less than perfect, or my tune may be off even a little bit will I be able to get this new bow to shoot right. I currently shoot a 420 grain arrow. Again, with my current set up and a 30 inch draw and 70lb wieght I have no accuracy problems, but am worried about problems that may arise with wind plaining etc.

Man, you have some good questions. I was also wondering on the speed limit with the slick tricks. Might want to shoot an PM to MeanV (Dan) and ask him. I would think he would have some answers for ya.

The higher the arrow speed the more any tuning or form issues will show....especially with broadheads.

I don't think you will have any issues shooting slick tricks at that speed. As long as the heads spin true, and the arrows are straight you shouldn't have any issues with the flight. If you do, then it is most likely a form or tuning issue.
