i'm shooting an Elite judge at 60lbs and 28" draw. i'm shooting easton fat boy 340's with 100gr nibs that my pro shop recommended, and like them pretty well, but i'm wondering if i'm over spined. I"m getting 277fps. will i get any faster with 400's? or should i crank my poundage up some? I"m trying to get some more speed out of them and might trying using some 80 grain nibs. I'm using this set up for 3d only so KE is not an issue. any advice is appreciated. thanks!
