I would have to agree with alot of these responses with using the CMB, it just makes the most sense. Thats what we run in all our scales. I also believe that the CMB simply is more consistent than anything since the picco. Dont get me wrong though, I do understand that other motors work, but it takes alot more work and set up time. You should talk to Mr. Phil aka Bday boy if you decide to try a mac haha. Dont get to crazy with a short pipe though, still gotta be able to win that milling battle that we have in all our finals in Dist. 14
