I built a new bike for the GF, and at the same time she was learning to use clipless.
Big mistake.
Never sacrifice a shiny new bike to a clipless newbie.
Initially, I put the A-520's from my spare parts box on it, but then realized that only made things worse, so I swapped the double-sided 520's from my touring bike onto her bike so she didn't need to also deal with trying to flip the pedals around.
