Actually avoiding an armour break wouldn't be that hard if you guys just used simple moves like AA or BB & stuff like that. The less impact you make the less you armor will break! Oohh I rhymed :DExacly, we even did purely gentleman show-off CAS session with Le Bello where we just decided to let each other win alternatively and tried our best to avoir any kind of armor break (which is difficult) to produce better material for pictures or funky replays with spectacular moves.
Eventually we got bored of it and got back to good ol' no holds barred :o)
I still like relaxed CAS non competitive CAS show-off, because it is relaxing (and i never do ranked matches anyways)
