ISCI Hand Brake Stopping Distance?

[pwpalmbay]

I also had a bad master cylinder from them last fall. They got a bad batch from Harley Davidson.
Yes the only Harley part on my bike failed. Great guys at ISCI sent one almost overnight.
I also am paraplegic and have nothing to compare it to as far as using foot brake.
I do think it could stop better with a hand Brake. My idea is to use a BRP clutch master to a second slave parallel with the ISCI unit. Then I can stop with both hands. The only custom
pieces would be at the ISCI pivot/interface and slave mount. Looks like a second parallel slave should be simple.
Found picture of used one on ebay. Second picture is from ISCI site. What do you all think?

My thoughts are this: with the ISCI set up as is, there are too many mechanical pivot pts that lose some of the energy in the hand pull that is actually transferred to the caliper. Maybe if the braking system was more conventional (strictly hydraulic), it would work more effective.
