I shoot a tru fire velcro also. Not sure if sure if the buckle would work for below freezing hunting with different thickness layers and gloves. I like the adjustability of it. I do have a tru ball thumb release that I got in bow package. Will have to experiement with that.
I have an older TruBall Loopmaster, I was ready to get a new one until I changed to a leather buckle strap a few years ago.
