Any thread on Esa, oil, or Sargent seats just run and run don't they...
On the off-road debate.... I think that it just makes sense that if you're going to do a lot of it you're probably wise to keep all gizmos and trickery to a minimum.
If you go off-road occassionaly then it's your choice...and your risk, if the vibration/drops/abuse will take it's toll.
If you stay on the road then you're back to the initial quandary of cost/performance/use etc.
It's worth on an off-roader is a different concern to most GS/GSA owners (I for one never wondered how going off road would effect it when I was waying up the options) which I think is Adam's point.
