I have a tru fire wrist and a tru ball t handle thumb release w/ a swivel head. The latter definitely has more advantages , just hooks on the d-loop, not getting in the way, and always ready to go.
For some reason I wore the wrist release Thanksgiving night and a buddy and I were set up 25 yards away from each other watching 2 different lanes in a yard, regretted wearing that one as it was just getting in my way with gloves on and with trying to communicate back n forth.
I chose to wear it as I'm gradually switching over and it was just a comfort thing, never again in the cold though. Those cheap little heat packs can become man's best friend quickly this time of year.
