I have an RMC Wizars and love it to bits. The only wah I've found that suits extreme gain or extremely bassy fuzz sounds but ALSO sounds pretty classic.
FWIW I hate the Bad Horsie II, both it's over the top voicing and it's switchless design, I think it's absolutely horrible and renders the pedal with a rotten action, but I only know one other person who doesn't think it's the business so...
