I would recommend tinting, but do NOT tint your windscreen! Else you end up like a person who crashed into a concrete block, then went on looking for to someone to blame for the accident, suggested suing the dealership for "installing illegal tint on his car" (he actually wanted to sue the manufacturer for uhhh... something else). I don't know if windscreen tints are illegal, but trust me, it's not something you want on your car at night.
