I got a silver pair from Rivendell a few weeks ago to use with my new-to-me Joe Appaloosa. I had a pair of $20 Clem pedals installed as a place holder and these are a big improvement. I'm used to retention of some sort: toe clips and straps or SPD or Look/SL style. It is amazing how well the little pedal spikes retain your feet over all but the biggest bumps. The overall length of the pedals, 4 ½ ", makes for great support and I feel less like I need to wear SPD compatible shoes. Indeed, softer, running shoes do a better job of holding a position and the long, wide platform of the pedal obviates the need for a stiff soled shoe.
Still getting used to them but very happy so far!

Interesting pedal arguments in this advertising heavy promotion of the Catalyst pedal:
The Catalyst is a little longer than the Monarch at 5".
