Premature clutch/master report
I say premature because I've not raced or broken it in yet. I installed a RPS Twin Street carbon clutch/flywheel combo, and at the same time, a Tick adjustable master cylinder, with a stock slave, and a Centerforce TO bearing. Absolutely NO chatter, even brand new. Also a VERY abrupt clutch take-up. Maybe about a half-inch to full engagement, at about 3" off the floor (about normal height), but it takes some getting used to. With the addition of the Tick, it maybe that the force required to push in the clutch has about doubled. That's OK, I'm pretty big, but I could see where some wouldn't like the increased effort. I need a good clutch to put down the expected 600+RWHP that I'll have after the SC install (which is done) and tune. I have to keep it below 4k RPMs until I get it tuned for safety with a temp tune. I promise never to attempt to install a clutch again, as it was a giant PITA. Of course I had to do everything together....the new cam/pinning, the SC, and the clutch/Tick. I ended up replacing the EWP for stock, and the ported FAST 90 for stock, which I probably wouldn't do again. The new components seem to do the job, and I'll probably get used to the new feel. Calling Tom Wong tomorrow about the tune, so I know it'll be done right.

Some serious stuff you have going on. 
I wasted money & time on a LS7 clutch this time last year & will change up to the RPS. It has been explained to me exactly as you described when using the Tick MC.
That is probably better with an aggressive driving style, I may try the stock Hyd. first
