Andrew, We just got Titan at my base in southern Indiana only 100LL and I don’t like burning it because my engine is cold blooded and fouls the lower plugs. I just put the ElectoAire ignition system in it and that has helped when I’m forced into 100LL and saves a bunch of fuel to boot.
Like you, I hope that GAMI or whomever doesn’t forget about the outposts when all the mainstreams have their respective fuels, but out in the sticks we have a way of being forgotten.
I agree that the STC issue is a big one. I had fuel bladder leaks too, but then they were OEM and 20 years old when I bought the airplane and run on nothing but AVGAS 80. The new tanks have been in for 34 years without an issue on mostly mogas. No leaks.
In the fuel debate, there appears to be little but politics, economics, innuendo and the like. Much like the mogas criticism I used to get in the '90s when the red juice went away. Half the mechanics I used swore by it, the other half at it.
