The first con isn't a big deal as I'm only using less than half of a tank per session, but a quick check of my regular tracks doesn't look promising for availability.

The only "con" is the decreased fuel mileage. I was daily driving 2 years ago on full e85 and am right now. After calculating costs it's much cheaper for me to run full e85 as it's $2.49 (in the winter) and $2.20 (summer) per gallon compared to 91oct that's $3.50+. I get about 16mpg on full e85 in SoCal traffic. The % of ethanol at the pump doesn't matter, but most pumps will be around e75-e85, this will map fuel for any blend of ethanol.
