My PTT is definitely lighter than stock. I'm using the PTT throwout bearing, which uses the backing plate from the OEM TOB to install (bearing is conical, OEM is not supported with my clutch).
To make mine more driveable, I have the 2g FWD slave cylinder, and the 2g accumulator tank and it still requires practice to get comfortable with (valets will hate you
)that said... I doubt I would run a twin unless I needed to- that being either high torque, or high RPM shifting. Otherwise they are a bit race-car-y to live with.
Southbend has some nice single disc options that turbowop and others have reviewed quite positively here.
