In the end I went with ACT's MB7-XTSS. The heavier clamp load with a street disk. I had spoke with ACT and they completely turned me away from puck style clutches; theirs and anyone elses. I also followed RRE's advise regarding puck style clutches;
"Whether it is a stock flywheel, lightened stock flywheel or a Chromoly flywheel, puck clutches make cracks that kill flywheels, that kill bell housings and more. They have their place but I don't think in a street car. In a race car that gets regular inspections they can be fine."

I had my doubts about this till I came up on a dude selling a used Exedy with about 5k miles. I took a look at the flywheel and there it was; a crack in the friction surface. The flywheel wasn't even heated up with no discoloration. My stocker I took out looked worse, blued to the other side and uneven, but without cracks.
I have a street car. I'm sticking with a street disk.
