I'm currently using the Touratech mount for my 2610, plain vanilla one (no lock, not extra anti-vibe one). Like all Touratech's GPS mounts they are a work of art and if cross brace is your mounting place of choice then it should get consideration.
However it does have a MAJOR drawback in that the metal closure bracket which clamps the top of the GPSR unit also obsures the internal antenna and compared to every other mount and loaction I have tried, miGSel Mount, RAM Mount and Garmin Cradle, the reception suffers a lot, really requiring an additional external aerial.
For line of sight the miGSel (for 11XX) cannot be beaten or the Motorrad Concepts for the 1200. I normally use a miGSel 1150 mount on a short RAM arm with a Garmin cradle, which having an additional locking screw gives me more confidence the GPSR and cradle are not going to fall out with each other on the road.
