you are fine with what you have...like others said...Go with a fixed broadhead, Some states dont allow mechanicals. Practice Practice Practice!! Me personally I would stay under 40yds shots...I have heard of shots out to 75yds with a bow but Im not that good and I dont want to risk wounding some animal. I am confident at 20-30yds. A broadside shot in the vitals with a good broadhead is going to take the animal down.

You are fine. Check out the 125 grain Thunderheads too. They have worked well for me. Being long armed I pull a 32" arrow, and I still shoot glove. Tried the mech release, and don't care for them. You should have pass through with your setup easily.

Just for fun you should check out Toxic Broadheads
and Solid Broadheads
