Excellent film, very well done. If I may, let me add a couple of points regarding "technique", in other words, how do you fly a good rolling scissors and what is your reference point. In both a rolling and flat scissors the objective is to get or remain behind your adversaries wingline forcing him to fly out in front of you. In other words, you want slower down-range travel than he has. The key to doing this is to keep your lift vector behind your adversary, a point called his "extended six". This is how you ensure that your helix angle is smaller than his. Most people just roll to put their lift vector directly on the adversary. This is fine if you're pulling for a shot but in the rolling scissors will equalize your down-range travel and, at best, keep the fight neutral and at worst you will lose any position advantage you have. By pulling for a position on his extended six you have the best chance of staying behind his wingline and forcing him out front. Also, as with any vertical moves throttle control is important as too much speed across the bottom will increase your radius and cause you to arc giving your adversary an advantage.
