Paul, I have a shiney and am continually ribbed about it. I have had the 110 over Drumclog quite a few times and apart from the Valley of Death as they call it (up by the pipe) I go anywhere else on the site.
maybe I have been lucky but the only "injury" was a nick in the wire to the ABS sensor from a stone being flicked up.
The secret on this site and any other for that matter is to go with folks who know the site and who know how to drive the various sections that challenge you. With the right kit you will be extracted from the mud.
There is also a site at Shandon over by Helensburgh that has a good selection of tracks.
