Or how about c) decide that the KOP tranny is the best one for their application? At least one of the 2005 champions decided that the kit trannies would provide what they wanted (strong, cheap, good gear ratio, easy maintenance) and went for it. Then in 2007, they decided to use an AndyMark 2-speed for the same reason--they knew it would provide what they wanted.
