I have a clutch specialties 2900lb pp and 6 puck disc. I like it.

As for act i'd get a 2100. 2600 has been known to break shit. Though I have a 2900 CS I think it engages better than a act 26. My pedal isnt very heavy but when it engages it doesnt play. I had to get used to it from my worn out clutchmasters.
