Advice please? Abus 72/40

Hi folks - I can pick my Paclock 90A and my Master 410 LOTO, but I've got a couple of Abus 72/40's that are essentially black magic to me. I know that unless you're a lockpicking god like LPL, a fair amount of the battle is figuring out which tensioning tool and pick works best for that particular lock, and you can also have bad luck with ugly bitting. But even so, I'm utterly clueless with these Abus 72/40's. I'm assuming top of the keyway tensioning, but can someone give me a clue as to which picks work best for them?
