RE: Arrow weight for deer.
I'm with Silentassassin... I don't consider anything below 55 foot pounds to be PLENTY. I have one setup at 72 and one at 65. I feel a proper hit will get me a passthrough. If I hit the shoulder on a BIG deer I hope to poke a hole in the offside but probably wouldn't get a passthrough with the 65 and questionable with the 72. Depends on where you hit the shoulder. I've hit both and gone through and I've left it stuck in the off side without coming out. All depends.
