does anyone use 100LL av gas ?

Ran it in 2 stroke bikes since the 80's with zero problems, all the dirt bike magazines of the day published stores about how bad it is for your engine with the same list of reasons I'm reading here.....three pages later they had an advertisement for their favourite race gas.
Now I will say that you do have to tune for it, if you run it in cold weather ( think snowmobile ) you will have to jet and time it for AV gas as it does not like to start like pump gas in cold weather.
It's also not a blanket replacement for all race fuel by any means but for some engines it is definitely something that could be used.
