Any particular reason you picked a puck clutch for street use??

Warranty is always a bonus, puck clutches have a higher torque capacity so it tends to take abuse better than a full face clutch, puck disc have less rotating mass so the lighter disc allows you to shift faster, the synchros in the transmission do less work to match the speed of the input and output shafts since there is less rotating mass on the input side. I could've gone with a lighter flywheel but from past experience they usually knock @ idle, (may not be @ initial startup, but usually once broken in it rears its ugly noise) and running an aluminum flywheel with a puck clutch will eat up the aluminum pretty fast. So for that reason I tend to always lean on a steel flywheel.
 
I have put on about 75 miles and it does have a bit of low rpm engagement chatter(which I expected), but if you ride it out with a little more RPM it engages fine, so far this clutch doesn't engage like a switch ("on/off") like some I have driven. Also in stop and go since we have a hydraulic clutch your leg doesn't feel the additional weight of a heavy pressure plate.
