i commute to work and back, and the last thing on my mind going to work is a puncture, so i switched to slime filled tubes, if the ubes do there job and get me to work on time after a puncture then great, the wieght is very slight, i think its personnelpreference, dont go with the crowd just cos they say slime is crap, do what you think will be easier for you.
if slime gets you to work, or gets you home then its done its job
