I can echo the above entyrely (ho ho ho)
Ran a set on my wee all around scandinavia (getting on for 7k miles) and they've been great. Enough grip in the dry to scrape pegs, certainly. I'll get some pictures if I'm able - I put a lot of motorway miles on these, and the rear has squared off noticably, but I can't feel it while riding.
Only possibly downside imo is the noise - I don't care, but some may dislike the hum I get ~70mph. And decelerating through ~35mph they hmm a bit too.
Other that that, a bit vibey at really low speeds, but no issues once moving.
They've been great on the scandinavian roads, and have got me through mud (dry and wettish), loose gravel, a few bike lengths of deep sand, wet grass, that weird scored tarmac...
