does anyone use 100LL av gas ?

I was wondering if anybody uses 100LL av gas and what there experiences were/are ?
And here is my original Point again that wasn't any point at all it was just asking if anybody has used it and what their experiences were not opinions on whether I should or shouldn't use it. Or if I was seeing somebody else use it and wanted to use it to. I've used it in my brand new motor from original break in to the last time I took it to the track. I took the heads off this last winter and seen nowhere or anything bad that I could see it all. I was wondering what other people's experiences were with the gas if they were saying or adverse. As far as monkey see monkey do I don't really know of many others that run with it I know I have a friend that used to mix it 50/50 and has now went 100% av gas. Again I like the cleanliness the consistency and so forth. And one more time also I don't believe my motor is so badass that it needs it I just like it.

The point I was trying to make is, there is a lot of monkey see, monkey do, without knowing why. I don't know enough about fuel chemistry to know if it is OK or not. I do know there is more to gasoline then the lead, and the octane rating. A couple of things that come to mind is the Reid vapor pressure rating , and the temp of vaporation. If you go to some of the race fuel sites, you can see the number of points of comparison of the different fuels.
