I must be the odd one. I use a liner and slime in my tires and keep them around 60 psi. Yesterday I ran right through the middle of a large cactus patch. i was picking spines (some rather large and thick) out of my tires and kept on riding with no flats, leaks nothing!
Well I don’t have to worry about cactus in Maryland thankfully, but I have seen and picked up a rather nasty thorns before. I will probably leave my tired/tub setup alone until I get a flat then decide what to do. I think if I start getting thorns though I will try the gel filled tubes and see how they hold up and how the extra weights affects my riding.
