I also have the M324's. I orignally got them as a first pair of clipless for my new road bike. I liked them so much I got another pair for my hybrid. A few months ago I got a new pair of shoes and found that the platform side of the M324 got in the way - apparently the recessed part of the new shoes was deeper than the old ones. I compromised by getting new pedals for the road bike and only use the new shoes on that bike. I use the hybrid for commuting and will make sure that my next pair of shoes can be used with the M324's! Overall I THINK I prefer the M324.
