I picked one up last week and in the end we settled on a mini trangia with an extra pot (from a model 27) and a home made wind shield.
The extra pot was deemed necessary and the space between it and the mini pot holds a lighter, tea, coffee etc.
All stored in a wee pouch to keep it together and keep the rucksack clean, it also holds fuel in the bottle from an army trangia.
Obviously this increases the weight over the standard mini but still lighter and more compact than the model 27 it replaces.
