If I were inclined to build a 243, the AI would easily get the nod. It wont' cost a dime more, save for the dies, and why not take the advantage and attempt to keep the turbulence point in the neck on top of it.
Even if you are like Brad..... the node isn't at max, it'll still be humming right along. If Brad went 243, and had to back off to find the node, he'd be another 100 or so fps slower.
Just because its AI doesn't mean you HAVE to drive it that way but at least you have the option.
