The guys hit the nail on the head with this one!

In my opinion, Speed is awesome! Nothing bad comes from speed! More energy=more penatration.. Animals can't jump the string as much etc.....

But, making a bow shoot comfortably with 350+ hasn't happened yet! If I could magically make my black ice shoot 400 fps. And change nothing, I would do it. I love all the PSE commercials about the x-force. "The smoothest Bow I have ever shot" BULLSH*T!!!!!!! Either your lying (because they pay for your hunts) or you have not shot very many bows! I shot one and it is fast as hell. But not smooth.

Faster bows to me equal one problem though...(my opinion) People are going to extend their range for taking animals. Not saying that it can't be done. Because we all know it can! However, the best part of bowhunting is the CLOSE ENCOUNTERS... That is the beauty of it. If I had a Bow that shot 500 fps.... and 1 pin out to 80-90 yds.. I still would not shoot a game animal at more than 50 yds... Point in case, I had a huge bull elk tearing the crap out of a tree 50 yds in front of me this year. Broadside, Perfect, I drew twice. But couldn't take the shot! I let him walk. I practice out to 60 yds regulary. But I truly love that animal to much to put the odds against me with a poor shot. If you hit a bull at 50 yds in the shoulder.. See ya, he is gone. Not worth it!
