I've always preferred the weight for penetration especially for elk. But i'm new to the carbon world so I really can't say. I know a miss on a target that hits a rock pretty much has the same effect on the arrow, it's a dead soldier. Time will tell for me. I trully don't know but my ole alums were always on the money.
Yeah, I was an ole die hard fart too but the carbons you'll find out that those pins will be tighter because of the speed. Don't worry about k/c, it will be there.

There is a big difference in KE and momentum/carryingweight... Yesa fast arrow may have a very similar KE ratingto a heavier slow one BUT... KE is measured upon impact. It takes alot less to slow down an 300gr.arrow traveling 300, than it would to stop/slow a 400gr. arrowtraveling @250.

Here is my pro-elite. First is @ 400gr. 60# 30"DL 305fps IBO




Total Arrow Weight:
400

Bow IBO Speed:
305

The second is the same bow figures, but with a 300gr. ibo weight arrow

ONly 34fps different, but the extra KE + momentum of the heavier set up would be far worth it imo. Finding a nice median is the way to balance speed, but not loose momentum.I would say a 380gr. arrow would be anice setup if i were to hunt deer with that particularbow. Last year was my first year hunting with a bow shooting over 275 (it was shooting about 300 with a mid 300gr. arrow weight) and it was no better for killing deer. 20fps or so isnt worth a pass thru for me...
