I shoot what I hunt with, minus broadheads of course, and of the TBOT courses I've shot none of them were set up where standard hunting rigs/equipment couldn't do the job. My bows are set up in the 9.5 to 10.5gpp range.
I'm not out to win every match I shoot. Would I like to be in contention or at least in the mix, sure. But 3D is about more than a buckle or my name at the top of a sheet of paper for me. It's about testing myself in non standard shooting situations on targets at varying distances. It's about shots more realistic to a hunting situation that help me be better when that real shot comes. So I want that to be with my hunting rigs.
