In reply to ralphio: FWIW I use a cheap £10 Pocket Rocket copy off ebay plus a 2litre titan pan.
If you want to spend £25 extra on a Micro Rocket to save 30g, then go ahead but I think it'd be one of the least cost effective weight saving purchase you could make. Also, when I'm cooking for 2 (or 3) in the Alps I find using anything smaller than a 2litre pan is just a complete pain.
That said, either of the options you suggest would work well enough.
