I like the ACT stuff, so I'm not going to disagree with your logic in that direction.
Have you driven the 6 puck/streetlite? It is quite grabby even on upshifts I can only imagine that the 4 puck/prolite is even worse. less rotating mass is good, but upsetting the car is also bad. Just something to consider.
I assume you mean flush not bleed which sounds good. I had them put Motul 600 in my clutch and put in a stainless line at the same time. I'm hoping the fluid should last as long as the clutch because taking my top mount out to flush it is no fun.
