I like mine. I've had the rear on for about 5,500km (I figure it's about half gone) and the front a bit less.
Really like them in the gravel and they have been ok in the sloppy stuff so far:
Absolutely no issues on dry tarmac either and they don't put a foot wrong in the wet unless you really push them or hit a painted line or something slippery.
A mate gets 12,000km out of them on his Tiger - I doubt I'll get that much but they were a lot cheaper than the K60's I had on last time and I prefer them to the Heinies on gravel. I only got just over 9,000km outta my Heiny rear, over 11,000 from the front (still had some life in it when I replaced it with an E-07).
