Not that it makes any difference....(as I don't know)......but if I straighten out my arm....the string's gonna be off my nose (with the shorter DL). I know that's not imperative....but I'd lose a point of reference.

If I extend my bow arm....where's that gonna put me anchoring? it would "seem" it's gonna have me hanging out there.....with way less reference.

Interesting, for sure.
