I was shooting a 425gr. arrow 285 fps, holding 76.67 pounds of KE. Now I shoot a 368 gr. 310 fps. holding 78.54 pounds of KE.....AND, I have just a bit more than 1" less drop from 20-30 yards.....Sounds like the lighter arrow wins for me...
I'm shooting 268 fps with a 500 grain arrow. All bets are off when that lighter, faster, higher KE arrow impacts the side of a mountain goat clinging to a cliff with every muscle tensed... Then it's all about arrow mass.
I agree that just for deer I'd go with the lighter set-up though.
