Yes, there is much to recommend Skyyr, who is both good at the blackboard and in the sim. Unfortunately, I've been on the receiving end of his fire twice now. The first time, I was doomed. I was rtb'ing almost on fumes. He was high in a 190. The second time was more of a challenge for him but ended the same way. As for the blackboard, I use his logic regarding going vertical after the merge all the time now and it works. He counselled, post head-to-head merge, that you pull vertical sooner rather than later since, if the bird you passed reverses, the immediate zoom presents him a more difficult nose up angle if he wants a shot. Generally, because I tend to engage cautiously, my zoom actually takes me out of their plane of turn or possible nose-up angle and leaves me with a nice advantage. It is then possible for me to roll to put my canopy top towards the target and flop back over for another shot. At least that's how it works against a turny bird.
