Currently shooting a Bear Strike at 60# and 28 inch draw. Arrows i'm using now are Easton st excel 400's. Grouping is decent but i've been looking for a heavier better arrow. My question is now, would i benefit much if i upgrade to Easton FMJ's at 330/340 and replace my 100grain with a 125? Not sure how right i am, but i'm kinda giving up on speed with my bow and going for energy. Correct me if i'm wrong in going this way about arrows.

Any and all info is helpful.
