The backstory...

Ever since I created my SPE Featherweight, the game now spawns it as AI traffic more frequently than any other plane. The plane uses negative weights, so if it crashes, it causes some minor lag.

And now for the suggestion.

It would be great if we could choose in game what planes will make up the bulk of random AI spawns. We could perhaps be able to choose 2 planes be the prioritized planes that could be spawned.

The benefits...

This solves the problem that I am currently having (It isn't much a problem really). It also would allow players to customize their AI traffic, and be able to see the skies dotted with their favorite creations, instead of a bunch of boring twin props.
