The thumb release increases draw length dramatically. Also, a right handed archer would need a left handed bow due to the way the thumb rolls the string during the draw. The arrow would very likely fall off the bow if you tried that right hand draw on a RH bow. The kantpinch is a very good tab, and you should feel no loss of sensation with it. I make tabs and some guys like mine, some don't. Most traditional archers will cycle through several until they settle on what they prefer. One VERY good commercial tab that I feel is underrated is the Saunders Pak-tab. You have the option of building it with their components in one kit....and....it only uses two screws to turn! Gloves can work ..I mean, kook at Byron Ferguson and Howard Hill! But, also look at most competitive archers, where accuracy really counts...and they are using tabs almost exclusively. Lastly, as a string builder, I can tell you that a 58 inch amo bow takes a 54 inch string, not a 58, which would just sit on the bow slack.
