PepeM, you get better power transfer by having a slightly longer crank arm on the drive side, say 175 vs 165 for the NDS.
Think about it, it's simple physics. The side with the spiky bits gets pushed in bigger circles because that's the circle that moves the little metal belt thing that makes you not stop.
I think it's safe to say that
IF you're spinning out in your 12t, you should probably go to a longer drive side crankarm before upgrading to an 11t.
