Top notch.
2 notes:
-the torque is the biggest blessing of the 109s (190s too)
-"chop throttle, he will fly right by" Its all about energy (plain outturning, outcimbing, rope) vs angles (overshooting, reversing, etc). In a same planes duel, the key is to judge the opponents energy state. If he has more, you can either use your lower speed to gain better angles or try to equalize the energy states (he might gain some angles on you during this process). If you have more, dont waste it unless you have a clear opportunity to get a sure shot on the opponent. After you see every fight from this point of view, comes the freestyle: doing silly moves what gives you a little chance for winning but at least you look good while being shot down - or just sweeping the floor with the opponent in 2 turns.
