Ultra Gatorskins are good. I had one puncture in 2 years.
I've also been using Bontrager Hardcase lights. No punctures in 2 years, though the Contis are quicker.
Had Bontragers on the OCR1, but picked up a few punctures with alarming regularity. Always carried a spare tube with me, but the bike went lock stock and barrel including shoes (got a very good price so it was hard to refuse) so I'm starting from cold again
