Thanks Vanoord.
Chris I must be half asleep mate, of course that makes perfect sense and is obvious really! I saw some 2 metre ones fairly cheap, I might treat myself to a couple next payday 🙂
That's a lot of space in your bag though on top of ropes, krabs, mallions, srt kit, cameras, tripods, torches, dinner, drinks, etc.
Something just long enough to wrap round a bit of rail or iron pipe seems lighter/cheaper.
