I've had Evo's last a season+ on outdoor tracks that are by no means "nice." I have some G+'s waiting to be glued up and expect similar, but make no mistake, they are 100% race day tyres.
Interesting. I had the opposite impression, though of course it's a slight difference as both tires are very, very light. I have a Speed on the front and an old EVO Pista on the rear, and to my eye the tread seems a hair thicker on the Speed, and the Speeds seem to have some kind of minimal coating on the sidewall, while the EVO's are bare. Whether this translates into any practical difference in durability is, well, who knows.
