I am shocked that the OP was paying over $70 for GP 4-Seasons. PBK has them on sale for about $40 often enough to meet anyone's needs. I always have a few in the closet. Don't forget to get a coupon code.
I'm unwilling to change from the 4-Seasons because they are the only tire besides the Armadillos that can withstand the sharp grit my county puts on the roads during the wet season. While the Armadillos do last, they roll like a rubber coated, squared-off piece of concrete. I rarely use anything narrower than 25mm, but I am 200 pounds and our roads aren't exactly smooth.
