I used to have Frogs on my roadbike but [1] didn't like all that much float.. especially universally, [2] didn't like that I had to go toe-in and [3] they required special 2-bolt style SPD adapters to be installed with my Sidi road shoes and I even had to modify the cleat box of the adapters... the whole setup added a lot of stack height and flex and was rather hokey. I switched to Zeros and all my problems were solved since they mounted nicely to the Sidis, I could adjust inboard/outboard float independently and I can just stomp on them to click in.
