I' d agree with ya 100% Buck Magnet, nothing but benefits to speed, all other things being equal. You' ll have no drawbacks, if you take the longer bow shots, say 35yds plus, you' ll have a little more room for error in range estimation, as well as a little more KE.
It' s when people think speed is more important than quiet, forgiving, woodscraft, stand placement, practice, etc, is where they run into problems.
