SOTO: interesting idea to put a pressure regulator into the gas line, but ...
* It does not boost the pressure in any way at all, despite some ridiculous marketing hype from some retailers. Chalk that one down to pure ignorance on their part.
* The claimed advantage of a constant flame height does not offer any benefit in the field in practice - why should it? I vary my flame height anyhow while cooking.
* The CO emission is worsened by the presence of the pressure regulator for technical reasons.
Well-made stove, interesting regulator control, but ...
Switzerland: Chamonix to Zermatt, then the Alpine Pass Route or Via Alpina from Sargans to Gsteig, then own cross-country route to PlanPraz above Chamonix, then GR5 and Balcon du Leman and cross-country to Thonon. ~6 weeks.
Europaweg trail to Zermatt: active avalanches bombing it and impassible (wiped off the mountain) in one place. Risk to life. We aborted.
Route 82 from Col de Sanetsch down to Godey: Poteau des Etales section: rather dangerous when dry, extremely so when wet.
