Someone argue with this..... Shot from the SAME BOW, nothing hypothetical here. Real world numbers.......
350 Grains at 300FPS yields 69.87 ft lb KE
500 Grains at 254 FPS yields 71.55 ft lb KE
At 350 grains and 300 FPS your arrows trajectorydrops 22.92 inches from 20 to 50 yards and loses 4.15 ft lb of KE from 0 to 50 yards.
At 500 grains and 254 FPS your arrows trajectory drops 34.34 inches from 20 to 50 yards and loses 3 ft lb of KE from 0 to 50 yards.
SO, in essence you flatten your trajectory 11 1/2 inches while only sacrificing less than 2 ft lb of KE with the lighter faster arrow setup.
While I do not hunt at 350 grains, I am just proving a point here.

I don't think that anyone is arguing the trajectory factor that's pretty obvious to anyone. But the trajectory doesn't matter AT ALL if you know the distance your shooting and you can hit what your aiming at, at that distance. The only thing it realy does affectis your pin gap and makes the error smaller when you misjudge the yardage or want to shoot one or twopins.

But lets look at the "advantage" in reaction time the faster arrow provides... (and no these facts are not "misconstrued")
Fast arrow: 310fps / 5280 fpm = .0587 mi/sec x 3600s/hr = 211.36mph
Slow arrow: 280fps / 5280 fpm = .0530 mi/sec x 3600s/hr = 190.91mph
So at 20 yards it takes .19s for the fast arrow to reach the target.
It takes the "slow" arrow .21s to reach the target.... 2/100th's of a second hmmmm... That's as negligeable as the difference in KE.
So, shoot whatever you want, and nobody else cares.
