For as often as JTLE would be useful, I think that x' (U' D) R2 (U D') x + OCLL is pretty good. That alg can be done very fast, because you pull both the U and D faces simultaneously, and an x rotation is hardly worth mentioning (just a minor regrip).
Why not just M' U2 M?
Maybe because of this? [...]
Actually that was reply to Matt, his way of doing inserting the cross edge seems pretty silly to me.
I think it's probably faster than a Y rotation.
