Are you running Sylvans with clips n straps?

I switch from BMX platforms to SPDs to Suntour Cyclone with clips (old road pedals kinda like Sylvans but smaller and no teeth) all the time and don't notice too much difference.

Vans on the BMX platforms hold plenty well, good enough for climbing IMO.

The hardest part is remembering that I have to do REAL bunnyhops when on the platforms
