I had Wilbers fitted by revs a couple of years ago. I found the same, ie good but not fantastically plush. However after a couple of thousand miles it all came together and they are fab now, and I mean better than a really really good thing.
The shocks are also really set up for two- up fully loaded touring and when the bike is overladen that is when they work at their really best. It is just amazing then how the bike still handles like it is solo.
