I like coopers for all around. They last pretty good too.
I am thoroughly unimpressed with my Discoverer ATR tires on my K10, and fairly happy with my AT3 tires. The ATRs started throwing off chunks of rubber at 15,000 miles (3 or 4 years). The AT3 tires are good in every category, but after several sets I can't recall ever getting close to the 55,000 miles they advertise. Good in all other respects, though. Quiet and happy on road or mild trail.
