Park patches for on-the-move and if you have the time then buy Wilkinson's 90p puncture repair outfit which is an exact replica of the old Raleigh ones ( frayed orange edges, tube of glue etc. ) for indestructable repairs.
I use the slime glueless patches on my boardman because they are more convienient when on the trails, any other time i use tesco value puncture kit at the bargain price of 99p
