Main advantage is there is no spinning of the mousse in the tyre when rim lok used so much less heat generated.
If your plan to reuse your mousses then great way to get the most life out of it. If your using a new mousse everyday with a new tyre then maybe not as important, but I think of it as extra insurance.
I've seen guys melting Michelin M02 desert mousses in desert tyres without a rim lok at the Aus Safari.
