I tried Mr Tuffy tape a few years ago. It was absolutely crap. Thorns went straight through and into the inner tube. Slime filled tubes worked very well though.
Yup, slime liners NOT slime filled tubes. I've used the panaracer liners which for some reason don't seem to be quite as good. Slime filled tubes are ok for the small punctures, but seem to piss slime everywhere if the hole gets too big!
Stans or Eclipse tubeless conversion kit with Bontrager Jones tubeless ready tyres , you will lose weight and punctures will become a thing of the past IME .
I've used slime liners as well, think they're great. They do add a bit of weight and do make the tyres seem a little more solid. I hardly ever puncture, in fact I punctured once in 2005.
I've got the Mr Tuffy tyre liners. They do add a bit of weight but I haven't had a single puncture in the last year. Didn't stop me ripping the valve out of the tube though.
