What Gas should I use?

[red82gt]

I know that for pump gas using the lowest octane you can run on is generally true, but I've also read that a well blended race fuel will result in a denser, cooler mixture and on a hot day I would think that to be worth some power, especially when the air is hot and dry enough to start a fire with snapping your fingers.
I'm going to make a couple runs with 94 pump gas and then try mixing in a couple of gallons of 103 and see how it goes.
It'll also be my first time running on M/T Sportsman pros, so I'm pretty excited.
