We should develop an alternative here, something that doesn't cost a grand. Like why not a thumb lever like an ATV throttle? Or maybe a second caliper on the disk that uses all mountain bike parts, and you cram that second lever in there somehow.
I am still staring at my decompression lever, thinking that's clearly the solution, though I get what you're saying Bruce about it being weak and likely not up to the task of hydraulic braking. Still, just seems too easy
