I'm still faithfully using sector 32..
I buy a load at a time from A-tyres, and even though they are in France, they arrive within days, and so far have been the cheapest...
Sector 32 don't have the out and out grip you might get with such as Conti GP 4000 S with black chili etc, but I know they don't, so ride sensibly.... (and I've become a wuss downhill in the wet, anyway...)
They tend to do between 5,000 & 10,000 kms but occasionally they can suffer severe cuts, which have never actually ended a ride, but once the sealing becomes a bit pump, ride, occasional plug pop out, successful reseal, ride, pop out, sequence repeat, I take the hint and fit a new one...
I've not really tried patches or plugs, but then again, I'm generally too busy riding....
