Yen, just fyi, I have had Frogs on my Sidi Dominators also, and am about to put Quattros on the Dominators. So those two types of cleats can also be used--you just have to carve a little off the bottom of the shoes, and the LBS can tell you how to do that.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
