When I had to choose, there wasn't as many options, so I went with the McCleod Dual disk street. No complaints here, holds everything I throw at it, no driveability issues. Somewhat more expensive than the SBC, but it holds well and I'm happy. That being said, it sure doesn't look like you can wrong choosing SBC. In my opinion, Peter has shown his concern for our interests and stands by his product. Whichever you choose, pick your installer wisely, this is key to how the clutch performs IMHO.
