In my experience, a lrr is virtually always a big PP. Especially from a weak player. In that case we are WA/WB here.

I would probably call down all the way from the flop, since I do not want him to fold a worse hand.

If I go for more aggression this would be mainly for metagame purposes, but against weak players there is less reason to disguise your play. And if the other players at the table think you are predictable that could be useful later.
