STrange, I ran Pro race 3s all season for a couple of years, never had a puncture. STuck on 4 seasons and punctured in about 100 yards at about 30mph (on the front). The 4 seasons were very stable whilst floppy though! Even if my arse wasn't at the time. No problems since though.
Mostly use a 32 knobbly set on my cross bike SS in winter. Bombproof!
