Heck, you don't need a mechanical to shoot speed, that's all a big myth, my friend! I've shot fixed broadheads at speeds in the 320fps range in previous years,( and yes, took game with them, too! <img src=icon_smile_big.gif border=0 align=middle>) and it's all in the arrow spine and the amount of paradox coming outta the bow that makes things "squirelly", not the speed itself. If an arrow is spined and tuned correctly and comes out of a bow straight and recovers quickly from paradox, doesn't matter if it's travelling at 100 or 1000 fps, it'll still do the job and have the same accuracy. AND, a faster arrow will have greater forward thrust behind it, creating less chance of side-forces (wind) to disturb it!(Like the difference in accuracy at distance between a 30-30 and a 270 Weatherby Mag--no comparason with the slower bullet) <img src=icon_smile_wink.gif border=0 align=middle>
It's all in the arrow selection and tuning,(and stabilization) as you cannot run the same arrow at 60 lbs and 280 fps that you will run at 60 lbs at 350. That is the mistake most guys make. (Doesn't work due to the extra force applied at the shot) The only opposing factor is that to gain those 350 speeds we currently need to run an arrow that is way underspined, but as stated, once the industry catches up in the arrow spine dept, we all will be able to shoot those increased speeds with no problem, and at lighter overall draw weights.<img src=icon_smile_wink.gif border=0 align=middle> Good shooting, Pinwheel 12
