I did the maths, based on this real testing. For a 5 day trip, for 5 boils/ day (my summer minimum) the starting weight, with fuel, for my new set up is within a mouthful of water of my speedster stove set up with 5 days fuel. It’s not the whole story of course and I do just like meths, so a minimalist meths set up will still be my bikepacking go-to. And I know there are lighter meths options out there too so I may well try a DIY cone or X- Boil soon. But for some (not all) use cases, the Windmaster/ HX combo works well for me for a cost and weight saving over some of the proprietary ‘system’ stoves.
The HX pot came very quickly from AliE by the way, maybe a week to be delivered, well packed and the last leg by RM. Lots of places to get the Windmaster, but beware eBay where there are sites selling only a case (read the small print) for 30 quid!
