Spent a lot of time playing with different preselection cuts and then settled for only making cuts where
I was cutting almost no signal away and the letting the MVA's do the rest.
1) decays like l+l-H where H->ffnunu
Even in cases where the ff are leptons the initial l+l- are more energetic
and those were being selected.
