Alejandro:

I'am using 80/20 mix that I can re-sell on the island, it's a stove fuel, works perfectly well on my turbines (PowerMax is 90/10), it works better than Coleman propane and won't ruin your gas lines, it's more expensive than propane or PM, but PM is almost impossible to get here. I haven't tried a trigger valve, but I can tell you that the valve orifice on the containers I use is a bit smaller than PM's, so it may not work, I use a brass tube to extract the gas.
