don't try the candys unless you want to ditch the frogs...you'll love em.
as far as lubing your cleats, i use a dry wax lube on my pedals intaed of triflow to keep crap from sticking but the first few times clicking in and out can be slippery.
dont use the eggbeater candys. the platform around the actual pedal restricts the movement of the spindle. plus the platform negates the use of the foursided entry of the original eggbeater. I have many friends that use eggbeaters (not the candys) and love them. so if you are going to try anything from the eggbeaters line try the originals. plus the eggbeaters shed mud like none other so any sand or mud or pebbles wont be an issue at all.
Something I was told by the Speedplay tech via phone. You're supposed to lube the pedals before every ride. It's not in the instructions but it does mention it on the web FAQ. I do so now w/ both my frogs and X3's. I had a problem shortly after getting frogs where they wouldn't release anymore. Now I lube regularly and it's no problem.
I did 2 races last week that seemed to clog the lugged soles of my Sidis. But I was able to click almost everytime w/o issues.
I've tried the Candy SLs, but it was much harder to unclick the left cleat on a dismount.
OK, got to eat my words. Rode Surf City yesterday, probably the most fun course of the year. Off camber runs, couple run ups, some muddy turns, etc. Great course.
And how'd my frogs do? Pretty crappy I'd say. They got stuck w/ mud about every lap, I even had to resort to kicking the mud off, which probably lost me a place or two overall. I'm going back to my Candys which I thought were too tight before. But now that I'm better at the mounts/dismounts, it maybe a moot point now. Plus, I can't fathom racing in the frogs in muddy conditions. For dry conditions, they'll be on the bike hands down. For slop, no way.
