I had Frogs on my roadbike before switching to Zeros and had to get special SPD-style adapter platforms (one of the reasons I switched to Zeros... didn't like the big adapters and such) for my Sidi road shoes. Unfortunately, the cleat box for the adapter was too small for the Frog cleats and it took me about 2 hours per shoe with the Dremel to get things trimmed to the point where the cleats would fit. It probably would have taken me less time but I was using a rechargable Dremel and the charge was only good for a few heavy-cutting passes before I would need to recharge it again. I should have bought a spare battery.

I gave the Frogs to a friend of mine (just switching over fromm toe-clips) after getting the Zeros and she absolutely loves them. I also gave her a set of old K2 Mag-Ts (basically Shimano 747 copies) I had kicking around that came stock with my MTB before I switched over to ATACs. I told her to try each of them out and just give me back the pair she didn't like. She said she found the K2 pedals impossible to use and gave up on them. 'Course her opinion was probably influenced by the fact that she tried the Frogs first. |8^)

BTW, I tried both Eggbeaters and ATACs before deciding on the ATACs and did find the Eggbeaters a little smoother. Both seemed to be equally good in the mud... unlike my SPDs. I however did prefer the ATACs because they had a platform for those small moments when I didn't want to actually be clipped in. I then read up and found that many people claimed the titanium upgraded ATACs modified by Stan of Stan's No-Tubes offered smoother entry/release... especially for lighter riders. In the end I went ahead and got the Ti versions and have never been happier with my pedals.

The downside to ATACs is the price. ATACs are double the cost of Eggies and the Ti version I got was almost three times as expensive. For the money, Eggbeaters look like a really great deal even when compared to the lower priced Time Aliums.
