Thanks for the feedback. I wasn't sure if going with a 12-27 or 12-29 was the better option. I would rarely, if ever, use a 29 but then when you need it, it is great to have it. If the jumps weren't too bad, I would probably go with the 12-29. The jumps on a 12-27 are something like 23-25-27. The rest of the cassette is the same between a 12-27 and a 12-29.
