You see....to assert that it changes the shooter's DL...you have to assume that there are multiple "optimal" setups for that archer....utilizing the same equipment.
That's pretty smple to understand, I would think, also.
IF the archer already knows he wants to use a Dloop. There's only ONE DL that will allow him to use the loop; release aid of choice AND to maintain proper form. If he changes the loop length, then.....his NOR the bow's (which will NEVER change) DL won't change. his anchors will (and his form will likely suffer).
I have a LOT....I mean a LOT of repsect for Greg/MO AND TFox's knowledge on most everything archery/hunting. I sincerely hope that isn't in question.
We've just obviously come to an empass in ideologies. I can accept that.
