I've had some quality issues with the rubber on these tires (there was cracking and perforation of the surface after a few months use on some tires). And while they had good flat resistance I found that the rubber compound was too hard and did not grip slick surfaces well. I donated my last few unused seca survivors to a coop.
I now prefer lighter kevlar bead tires and use these year round with no flatting issues. In particular, I recommend the gran fondo tricomp and rubino pro. Both can be purchased in the low 20s during yearly sales.
