Good answer! For that I might be talked into taking two biners. I was more concerned about space than weight. Still...we're only talking about a few seconds at best. It's amazing the lengths we'll go to just to shave a few seconds or ounces.
Also, I found that tying a slip knot right after the rings misaligns the straps and creates more problems than it's worth. I "set" the rings by pulling them close together, allighning the straps and giving them a good tug. I have yet to have any slippage using that technique.
