Thanks Yazid for your references,
I had been looking at thermo valves, I recently purchased an alloy 80 with a thermo valve.. The quality looks good but I am concerned that the hand wheels length may be obstructive when slung as a deco bottle. Any thoughts on this would be good...
When using a relatively wide swivel deco reg, the Thermo knobs are actually better than many of the shorter stubbier alternatives - at least with bulky gloves on. Reality is you probably won't notice.
