David Mitchell,
It is a very minor observation but when you un-brace a string follow bow and the top loop is snug to the limb, the string exactly runs along the length of the bow.
By contrast, when you un-brace a recurve, R/D or hybrid, with a tight top loop, you have two loops away from the profile of the bow that always seem to catch on things when loading/unloading, fall away from the bow, etc.
Even a setback bow, the string spans the setback from tip to tip if the loop is tight, thereby making an "arresting wire" by which to hang-up on.
I'm embarrassed I brought it up....sorry!
