I just have a strange q-angle, I think, because my knee will move inward even without pedaling (the test that the BG Fit uses is standing on one leg, then bending that knee--both knees will cross the center line). So he recommended a compact double partly for that reason, especially if I find that SPD-SLs or Speedplays don't work for me, and partly because 1) it's getting harder and harder to find a triple anyway on a complete bike anyway, and 2) the shifting is nicer and cross-chaining isn't as big an issue.

Miranda, it's interesting to hear you say that you want to switch to a standard double. On both bikes I've tested with compact doubles (the CAAD10 and the carbon Synapse), I've ended up in the really high end of the cassette on flat ground (using the smaller ring). It seems kind of silly.
