I've been on Z6s and Pirelli Diablos for a while, 25000 miles or so now, with occasional forays into cheap Sportec M1s and trackday take-offs... They're all the tyre I need, if they never make a better tyre I'll be happy enough. They're effective in the dry and very good in the wet- better than the Sportecs, and far better than a supercorsa or similiar in winter. they're also good for my short commute since high silica content tyres work decently when cold, and on most days they never get to full temp.

But I'm still interested in trying the 021, Storm and new development the Diablo Rosso- which is a sticky tyre made to last a long time rather than a long-lasting tyre made to be sticky. I've not heard from anyone who's actually worn one out yet but someone on SV Rider has 5000 miles on a rear now and it's still in good shape, that's good for a sticky. But they;re expensive.
