I think he is refering to a D loop...Just looking at it upside down...
I also shoot off the string, did a lot of testing for myself when loops became popular, I was just as accurate without one and being a firm beliver of the KISS syndrom [Keep It Simple Stupid] ...I choose NOT to use one and shoot off the string...I can "Robin Hood" arrows as well as any...
My set up is two True fire Buttons with the top being the nock point and a lower to prevent nock pinch that the release sits under...
I am not sure what you set up is but it has to be done right to prevent nock pinch...a Loop can be installed very easily also if thats what you prefer..
got a pic of yopur nock point?
