Default RPM's effect on clutch/hydraulic component selection for an LT1 T56 setup?

Just wondering what everyone's experience was with regards to how well the stock hydraulics work in high-ish RPM applications for an LT1 T56. Think of a shiftpoint between 7,200-7,500 rpm. Will the stock hydraulics work ok for this? At what point do you need the aftermarket Mcleod hydraulics? Are there any considerations in clutch selection for RPM, or is it strictly a power-level thing?

clutch is dependant upon power, launching at 7000RPM is gonna tear the **** out of parts, but it wont effect the hydraulics at all. shifting that high you cant have a stock computer, its limited to 7K

I'm not really concerned about launching. I've heard complaints of it being more difficult to shift quickly at higher rpms and other issues like that, and it seemed like it was related to the hydraulics and possibly the clutch selection. Just looking for others' experiences and general input to if there's any reason you can't successfully use stock hydraulics and a milder clutch if everything falls within the rated power except at a relatively high rpm.

Also, I don't have a stock computer.

Hydraulics will work fine. I had a Spec Stage 3+ and it shifted fine at 7200rpm, however now it has been replaced with another 3+ and it drags a bit, but I am fairly certain it's the clutch and/or pressure plate since there is drag at any given RPM.

the only problems i had with the clutch hydraulics were from install error. they never were a issue with me shifting at or close to 7k.
