Red, Eden, and all- are your discs hydraulic or mechanical?

I'm test riding a Volagi this week - not for commuting but for ultra distance. They want me to ride it at the Levi Gran Fondo Saturday and I was happy to oblige. I haven't ridden it much yet, but so far I really like it and am seriously considering getting one as my climbing double century bike (DCs where I need easier gearing than my campy outfitted Peg will allow). They're going to be offering hydraulic next year, which is probably when I would get it, and I wondered what peoples' take was between the 2.

Oh good old "N+1"*.


*Where N = the number of bikes you have.
