[DVBC] easiest MTB pedals?

[eric zwicky]

hey all,

my son is getting a new road bike, and is interested in clipless pedals. 
    he's decided that MTB-style shoes would be the best for him, what 
with ease of walking around and all, so for pedals that means usually 
2-hole SPD-style cleats.

so i wanted to ask the group about which pedals are the easiest to clip 
in and out of.    i was looking at some pedals on-line, and there are 
some crank brothers pedals that look like they have a large platform, 
which might be useful if evan wants to take a spin with regular shoes, 
but i have no experience with clipping in and out, and i don't know 
anybody who uses them.

what about speedplay frogs?  i think i have seen a few of them on DVBC 
bikes.

any other suggestions?   the main criterion is ease of clipping in and 
out.   the second one would be ease of use with regular shoes.    i have 
worn street shoes with my look pedals before and it's do-able, but they 
have a bigger area than some of these MTB pedals.

thanks in advance for your time and advice,
