+1 on that. You need to align all your pedals nicely and you're in more need of a leg less hi-hat than any drummer in history (most of us DB players have just the 2 pedals to contend with on our left side- 3 makes things trickier)!That's certainly an... Interesting setup. I dunno what to say?! I would suggest moving the slave pedal to the right of your left bass drum pedal. Then purchasing a legless hi-hat stand, mounting it to your left bass drum, and put the hi-hat pedal to the left of your left bass drum. That's confusing just to type... I hope your have better luck setting it up. You're definitely on to something. You're also definitely one-of-a-kind! much respect to you, but that looks tough to play!
Or get a 2nd double kick pedal and have your 2nd bass drum to the right hand side of your kit, like Stanton Moore. Dave Weckl used to do it too.
