go with the L
I have draws and biners in both large and small and am very happy with them both. I must say tho, if you are a true gram counter, go with the smalls and just put up with it while you are hooking, but if you don't mind a few grams the L is just about perfect. They clip positive, feel solid in every way and I find the opening on the larges to be perfect for clipping bolts and running the rope. I have used them in the gym, real rock, and ice, absolutely in love and while I still pre clip using some of my other draws, you can be sure I won't be buying and others but these for the forseeable future.
