I've been using loops for a few or more years now......but you know I'm not completely sold on them. I had to reduce the DL on my bows by up to an inch in order to retain my anchor points.
BRL gives you some pro's.
Con:
Your draw is affected by a loop. Right now without a loop, you attach your release, draw your string back a specific distance until the cam rotates and you reach the "wall". You are accustomed to this way of doing things....when you are at the wall, you experience all of the anchor points which are familiar to you.....string on the nose and some part of your draw hand touching your face somewhere. When you add a loop, you effectively add .5 to .75 of an inch to the back of the string. Your draw length is not changed but you have to draw .5 to .75 past the anchor point which you have been accustomed to. This may be easy for you to overcome by chaning your anchor point or not so easy if you want to stick with your "proven", and habitual anchor points. The worst case is that you have to reduce the DL of your bow.
Not trying to talk you out of one, but this is the experience of a person who shot many years without a loop and measured his DL using a bow without a loop. This is exactly where you are situated right now. With everbody shooting from a loop now-a-days, and if they bought a bow with a loop already installed, they measured their DL with the loop installed and this doesn't even show up on their radar. If you install a loop be prepared to change something else too.
If you don't go for the loop I would suggest you put an "eliminator button" on your string below the knock. I know you had a twin jaw release before and that release prevents the pinch (on the arrow knock) that a single jaw release puts on the knock. I always had a couple of these on my string.........they last a long time(couple years even) but if one breaks off you can just slide another up the string.
