Provided the bow is a forgiving one. IE... a 7 inch brace height or more, narrow grip, decent ATA length, smooth drawing cam(s), low shock, etc... I will take all the speed I can get.

Reason... The faster the bow is the heavier an arrow I can shoot at moderate speed of around 260 - 280 fps. I would rather have a forgiving bow with an IBO of 320 fps than an equally forgiving bow with an IBO of only 300 fps.

Given equal weight arrows the faster bow will generate about 10 more foot pounds of kinetic energy and a considerable ammount more momentum.

If there was a forgiving bow that would do 400 fps IBO I would get it.
