best arrow

[PAPA BEAR]

hello fellow archers,i am in need of some input on arrow penetration.i shoot easton 2512 ultra lites off my bows but am concerned about penetration with such a thick arrow.i shoot woodsman heads and i have had fair results but i really want to do the right thing by the animals i am lucky enough to look at with my limbs bent.
 they shoot great off my bows but is this the correct arrow to shoot ? thank you in advance for your replies.

I'd want something thinner and heavier.  What's your bow set up?

several bows and same arrows..shooting mohawk l/b for elk..54 # shoots fast so energy should be good. arrows are just under 600 grains with broadheads so weight is good..just worried about penetration. thanks
