I'm running a DBAir CS on my Nomad and I dig it. The climb switch really does live up to the hype. I'd say it's more plush & composed than the Monarch the bike came with, but I didn't lose a whole lot of the "playful" feel you described.

I'd also like to join the others and say great review. I appreciate that you guys don't hesitate to point out flaws or annoyances when you find them.
