I recently realized the joys of riding clipless, and I want to get a set of clipless/platform pedals for my commuter bike. I was wondering if anyone had opinions on either of these style pedals:

Shimano PD-A530

I like the way these look, but the platforms look like they might be slippery in wet conditions.

or

Shimano PD-M324

Not as neat looking IMHO, but I'm leaning towards these, as they're a few dollars cheaper and the platform looks like it'd be a bit more grippy in wet weather.

Thanks!
