Not a fan of the 3.0, not when one can get a 2.8 for pretty much the same. No HeadShock, of course. I think it was a fine idea (I remember Bicycling Mag editor(s) or whatever swooning over that when it introduced) at the time I'm just not a fan of. . complexity.
I almost bought one for 360, but my facilitator bailed and the lady wanted $160 to ship. . and raised the price to $400.
