To KBentley:
Our target market is shop/amateur bicycle mechanics, leaning probably more towards the amateur end of the spectrum. The clamping to a nipple then ratcheting is probably the leading idea, unless we can come up with a cheap tension tester (looking rather hard). Thanks for the feedback, every opinion helps.

To Bill:
The goal of the class is to redesign a user experience that we found frustrating. Personally, I've always thought truing was poorly executed, but that's probably due mostly to my lack of experience. I totally see why you think this problem is overblown, and this is precisely why I'm doing this market evaluation. Thanks for the feedback.
