The m324 required looking down almost always, then when the pedals broke in some, I assume the seals wore a little bit, and even when looking down it was difficult (for me) to flip the pedal to face spd side up. The m520 I can always clip into either immediately or press close enough to start pedaling and within half a revolution or so it clips in. I was worried about the small surface area creating worse hot spots, but they are no worse, possibly a little better. Other than being built solidly, for me I found no merits to the m324.

Possibly something like the a530 might be weighted in such a way that the spd side faces up, but m324 its prone to facing down.

Cool, thanks for writing back. I had either the m324's or something with a similar design, same issue, really didn't like them.

You're welcome. Now I need to try to find some stiffer/arched footbeds/insoles for the specialized shoes I got, they still give me some hotspots, although I am a bigger guy, the ones they came with say plush, so seems reasonable to think different ones may help, just not sure where to look for them at.

Also, I have read in a few places that speedplay light action cleats will work with zero pedals, can anyone confirm this? TIA

Theres a few people in the Road Cycling forum who've confirmed this.

[MENTION=423178]thin_concrete[/MENTION] Thank you! That is one of the threads I had read leading me to believe it to be true, but couldn't find it again. I was basically gifted a pair of stainless zero's, found them somewhat difficult to enter/exit. Took the cleats apart, cleaned, dry lubed, put back together and was careful not to over-tighten. They worked reasonably better but upon reading about being able to use the light action cleats with them, or using the clip out of the light action in the zero cleat, it sounded great, as I am no where near racing.
