What about 7''. I was just at jenson USA, and saw some Avid Mech's. I don't really want the hassle of hydro's (I heard they can be a pain) so I looked at the avids. I might get 2 7'' or one 8'' and one 6''. I (if I got those) would get the Avid Speed Dial SL ($50 for pair) and the Avid full metal jacket disk cable and housing. (That is all I need right? just levers, the disks and caliber thingy, and the cable and housing?).
All that comes out to about $233 or so.
