Ian, what sort of stove do you use? I’ve ought a piezo igniter for this trip. I’ve even told they work fine with gas (I use a pocket rocket), but not so good with meths/ethanol stoves. I always carry a box of waterproof matches just in case.

It came with my MSR pocket rocket, nice little stove but the igniter refused to spark on many many occasions - use a lighter or striker and spare yourself the agro IMHO.

Good luck to you all
