One flat is a very small sample to want to make changes. I'd give it more time. Flats seem as much a function of luck than of flat protection, in my view. I've only been on a brief ride on those 650A Col de la Vie tires, and they felt very nice. I've ridden them fairly extensively in 650B size and like them there, too. I have the Schwalbe creams on my all-chrome Sports, but that one's more of a show bike than a rider.
