couple observations: my 1Up trainer killed my conti GP 3000 tires, so i put gatorskins on for training and everyday riding and put the conti's back on for racing.
changing a tire is no big deal, you can do it in a matter of minutes. really!
as for the GP 3000 and 4000, i just love them, yes - bontrager wheels, and i actually found them with a pink sidewall.
but i dont use them for everyday, for flat protection the conti gatorskins or maxxis re-fuse or specialized.
