I wouldn't shoot a fixed blade that fast. I tried to shoot all different ones but when your bow gets that high in fps any little problem is glaring. I can hit vitals 3/3 arrows with my mechanicals from 60yrds I tried using muzzy's and couldnt stay accurate after 30 yrds. I tried tunning them too and couldnt get it to work with the help of the proshop guy. P.S. and where I hunt I do need 50yd shots that is another post that we will not get into.
