Just an update.... I've done some searching on the M505 pedals and it seems getting into (and out of) them is a common complaint, or partial engagements that I've had where they feel like they click in but kick my foot out after a few pedal strokes. I've never had the problem of getting out but have experienced the other issues. Also I read people who have upgraded to M520s and M540s notice a huge difference. I'm actually looking at the M780s now. Marginal price difference over the M540s and they will match the rest of the components, besides 60 something dollars for them seems pretty cheap. I haven't ruled out the Time pedals yet but there are a ton glowing reviews for the M780s and only a few of mediocre reviews for the Times. Not suggesting they don't work for the previous posters but I have to look at the odds that they will work for me.
