I agree Magic. I think at 50 pounds youwould be fine when you're in the zone...if the zone is 20 yards....However some situtations can play a role with slower bows....for instance ....alert deer....looking at you upon release....we all know there are times when deer "drop and turn" at the pluck of a string....obviously speed helps with the variation in arrow trajectory on a deer that is in the alert mode when you release....

but then I reflect back to the late 80's....When we tossed heavy 2216 easton aluminums at 31 inches....and we never had a problem......

I guess my final opinion would be......a relaxed deer at 20 yards doesn't know if you're shooting 230 fps or 312....A good subject that has me thinkin......

I guess the bottom line is....find the lungs with a sharp head....and yer home free.....
