My best information is that alcohol in gas has a TERRIBLE effect on common composite structures. Alcohol by itself isn't corrosive, nor is water. But if you have alcohol, you WILL have water mixed in with it and it's the mixture that's so corrosive to composite fuel tanks (strakes). You need to research this VERY CAREFULLY before you commit to anything.
I've heard lots more bad stuff than good about alcohol ... Jim S.

The research has proven that ethanol-based avgas not only is a suitable replacement to 100LL, it is actually a superior fuel.
My take is that "suitable" and "superior" are weasle words that have no meaning beyond what the user wants them to mean.
My guess is that "suitable" means the plane can get off the ground with it, even if it has to have aerial refuelling at the end of the runway and all the plastic seals in the fuel line are eaten away before it can finish flying the pattern. "Superior" would mean that they make a little more margin on it than 100LL. Of course, I could be wrong.
