Hi WestTnMan! I use the same tab and love them. I like to just have the leading edge come out a little shy of my finger tips when I bend them half way. I want the string to slide off the tab and my finger tips at the same time. I DON'T want the string to continue sliding off the tab beyond where my finger tips are. So you can just eyeball it. With the tab on bend your finger tips and mark where your finger tips are and cut at that line. Or you can put baby powder or talc on the string side of the tab and shoot with it on. Then carefully remove the tab and look and see where the rubbed off powder stops. That's where the string lost contact with the tab! Enjoy, they are a great tab. My accruacy has improved greatly since switching from split to 3 under.
