In the countless hours I spend at my local Sportsman's Warehouse and other local archery pro-shops, I decided early on this year that I was going to change out my release aid. Prior to 2008, I have used the T.R.U. Ball Loop Master. I have nothing but good things to say about the T.R.U. Ball release aids, however, I was after more than simply changing brands. I had been hearing bout the merits of "Back tension" and "Thumb Trigger" style releases. Anthony and I have, on countless occassions, talked about looking to professional paper and 3D shooters for the equipment that could make you more accurate in the field. Overwhelmingly, professional shooters use "Back Tension" style releases. Why? What do these types of release feature that makes you more accurate? Are they practical in the field?
