The Smarties (and MXRs) are OK, good even, for 4-5 months until they get gritty and don't turn so well. Since you can't rebuild em, they're trash. I also find that when you spend the $30-$50 on the nicer pedals the build quality and finish go way up.
Personally I am done with Eggbeater style pedals. 4 sides are great but even the platforms give me hot spots and they have too much float. I don't feel secure enough in them.
