Let's talk clutches, shall we
Until further notice, I'd stay away from Spec Twins.

I thought they didnt last a long time?
well I pulled my tranny today for first time in two years. I got to see my ATS carbon twin . I bought the clutch used with break in miles on it only. To my absolute amazement the clutch looks like the day it was installed. No wear on the friction material at all. I never had to adjust clutch in the past two years. There is virtually no highway miles driven. all hard city short drive lots of shifting miles. Nothing will outlast this carbonetic/ats friction material. It is hands down the best friction material made. Nothing comes close. amazed at lack of wear on carbon discs. there was no friction dust at all. usually have to hold your breath when removing flywheel bolts. dust flying everywhere. there was none at all. boths discs measure .0055 wear from new thickness.

What power?
I heard that you need to "warm up" carbon clutch to hold power at the strip
And that they suck for dd
Its just hard to believe how off are the facts
So if i can buy carbonetic twin or triple i should go for it?
Keep in mind its dd with 3-6 track events(drag)
Minus the launch and the shock value to the drivetrain, drag races are not really that hard on clutches.
Reason:
You go from a moderate temperatures on warmup to a hard slip on start, then moving into a power shifting or NLTS type shift all the way down the track. After the run, the clutch gets a full cooldown; now rinse and repeat.
Yes there are those that have 600+ hp monster drag only builds, and they choose a clutch relative to the application.
The other guys you'd probably want to talk to are the drift guys. I believe that is one of the hardest applications onto a clutch, esp. the Subie, or Evo (aka AWD) guys that do it.
Most of them have been choosing OS Giken for a lot of reasons. Most of the OS Giken clutches have been known to go through a whole drift season with good results.
OS Giken builds a fully caged design. If you look at the TS2B or the more race oriented Aluminum R2CD (from memory sorry) you'll see the cage interface has about 2x the bolts than comparable clutches on the market. I'm not trying to shout against other manufacturers but I think OS got it right with their design.
The TS2B is the clutch that is most used on the street Evos, and I have one in mine.
Good luck,
