I bought a Gibraltar Intruder double kick pedal (chain drive) a couple of months back and would highly recommend that. Really robust but plays in a really light and fluid way. Totally changed my double kick playing
I have a DW 5000 Turbo chain drive. Very good dbl pedal. Damn near plays itself Got it from Guitar Center used. It was a floor model for $300. Look around at GC'S used gear site.
Cheers
i would go with the pearl eliminator. the cam system realy lets you find your fit... i use the blue cams my self. for this price point i think they are a good buy.
