I've developed a slight variation of the hammerhead..
If I have enough speed and I see the enemy go for the rope, I push vertically untill I see he stops gaining on me.
Then I perform a loop from my inverted position to get a shot at his bottom while he is dragging his nose up. He has two chances at this point, either try to evade to the side, giving me an easy shot - or trying to push for HO which usually makes him redout effectively, blowing his chances to make an accurate shot.
