at the mo i don't really go any lower than 24psi anyway, but there's always a thorn or wire waiting to get you. I pack to much at the mo but thats from not wanting to get caught out from lack of experience.

I'm running the fitted tubes with oko sealant installed and carrying spare F/R. until i see it for myself i'm not convinced about using the f tube to replace the rear if it goes.

for me i'll be sticking with tubes, atleast if the tyre has a large rip or something similar with a new tube fitted you have some hope of getting somewhere to get recovered.
