Speed means very little in the grand scheme of things. Speed is really the last thing i'd look for in a bow unless you are thinking of shooting 40-50 lbs. Even at that, recurve guys are killing deer and getting passthrough's shooting 150 fps. Don't dwell on speed, pay more attention to valley, wall, ease of drawing, grip feel...is it repeatable... Way more elements to choosing the right bow for you than a name or dollar amount.
Ihookem, 236 fps isn't slow. To you maybe...but what is slow? so a deer at 20 yards is 60 feet, you don't think 236 fps is fast enough? Ask a recurve guy what fast is and it will change your whole perspective on judging bows on speed. I know a lot of hardcore traditional guys and they kill the crap out of deer. The problem with compound guys is they think they have super powers. a deer at 35 yards will duck an arrow at 350 or 150. it's all been proven time and time again. chasing a speed number is not the way to choose a bow.
If all you shot is 3D unknown, then get the lightest arrow possible and shoot 330 fps, that should improve your scores a bit. To shoot a sub 350 grain arrow at a deer is just asking for trouble. This thread has nothing to do with speed or arrow penetration, but most are buying a bow to hunt. i'd never chase speed and I wouldn't buy a light arrow. only way I'd chase speed would be if I was going to make a super heavy arrow and build that arrow for 650+ grains. Then at least that speed will benefit you
