I also preflash, look for lower contrast scenes, and try to develop carefully as possible. You can also use your warm finger during development to bring up some parts faster than others, or (I just learned) use ice to slow other areas. And you could selectively bleach out some portions after development. I haven't done SLIMT but why not. Sure.

Apart from all that, the obvious thing is simply to "get over it" and compose knowing what the tonality of the final image will be! Trying to make paper behave like film is going to cause trouble. Why not let paper be paper and enjoy it for its weirdness. You can take a pencil on the back of the paper neg and go to town and do something inventive...
