I'm glad so many people are interested in these. I'm planning to close orders next weekend and sometime the following week try to figure out shipping rates and start collecting cash. Don't forget to thank 12afael, he's the guy who designed these, I just prototyped them.
The 16mm carbon Omegs are what I'm using, however Colin has suggested that he could order some with 1/4" shafts so they fit more knobs so I'm waiting to hear back on that. I'll let you know, and I'll post the BOM and such soon.
