One thing I realiased about crosswind landings is that if you slip it in, you are dragging it in under power.
Depends entirely how much energy you've got, ie how low and slow you are to start with - start higher and you can slip all the way down.
(Personally I find dragging it in under power occasionally useful for short runways
with no obstructions in the undershoot, but no doubt I'm going to be shot down for saying that. And I haven't had to do it for a while, so maybe I don't need to any more.)
