Thanks for the reply Eddie. Makes sense to me that the draw length doesn't change. Arm distance will, to a small extent. This will be my 8th year with this bow and never used the d-loop. The area where the release attaches, still looks good. The bow shop, where the bow was purchased said they were not needed, so never went with one. I suppose their could be some getting use to a d-loop.
This is the original string. Everything is so nicely super tuned on this bow. Kinda like a super tuned wrist watch. I hate to have a new string put on, but know it's due.
