This is the method I used with my max size bow (I've gone to a crossbow, not being a front line fighter):
As most bows are recurved, you can take a length of stout string (thin clothes line) and tie it into a loop. Place the bow through the loop so that the looped ends do not pass over the recurved ends. Sling the bow over one arm and your head so that the bow is behind you and the string is across your chest. Now, when you un-sling it, the bow comes free of the string. With practice you can handle this as fast as if the loop where attached to the bow. And, in a pinch the string makes a fine Circle of Power phys rep.
