So I am on a quest of sorts. After playing with the GI issue cotton sling for my M1A I have decided it is inadaquate for my intended purposes. Don't argue I have made my decision

.
I am looking for a sling that can do the impossible, I want a sling that I can wrap around my forearm and get some decent shooting positions as well as be able to carry while on the move.
My problem is while the 1907 slings make for a great shooting platform I find them lacking in the carry positions department. I had a great 3 point sling that I sold with my last AR and I have thought about purchasing the same for my M1A however I could never get them to cinch in tight enough to affect my shooting. Also because of the type of rifle I will have I would have to get the loops that wrap around the forearm and stock and while I have never had the chance to see I can't imagine the sight picture and barrel tension would go unhindered. Barrel tension is important because I do not have a unitized gas system.
Without swaping out my walnut stock or installing rails and such I don't see being about to run much more than a standard two point sling that will attach to the loops I have available.
Any thoughts or opinions. I am seriously considering a Turner Leather Biothane AWS sling. This would give me all the advantage of the 1907 sling but with a synthetic durablitly.
I would like a few suggestions.
