Frank, I know this is blasphemy, but you really don't need a new bow to try this out

Just back one of your's down and shoot a lighter arrow at the targets

One of the new bows I am considering is a 70# Patriot SC set at 60#. I calculate it should fling my 375 grain ACC about 290ish at my draw length.

Wow...

However, I'll be plenty happy with my Hornet at 64# with the same arrow doing 280 if I can get that just sit's there feeling. Time will tell.
