I'm greatly in debt to the trainers -- Murdr, Widewing, Hammer in particular. I've also had great sessions with Badboy and TC. Lastly, the training films put together by Batfink, Badboy, and TC were absolutely perfect for my learning style...wish there were more of them! Without what all these guys have taught me, I'd probably have given up on the game long ago. I don't believe I'm a fearsome stick by any means, but without those guys' dedicated contributions I would be hopelessly outmatched every time I fight.
But -- for whatever reason I'm really, really bad at making myself go in for training. Every time I've wanted to start a "program" of practice, something inside of me just dreads going into the process. Maybe its that it feels like school, or that my innards get restless when I die and die and die to the trainer, or that the practice work isn't going to have enough fun to be relaxing. After all, AH is recreation for me, usually when I'm tired out from a day of work.
So here are some alternate ways I've found to get the training and skill advancement you're talking about.
1. Reviewing films off line is great, especially when done over and over from different perspectives each time. Gotta make sure you watch "actively", thinking and imagining while the film plays. Watch the fight from inside the cockpit with original views on. See what the guy was seeing, and guess what he was thinking, how he prioritizes the opportunities and threats. Then watch from outside with paths on, and try to see what classic BFM moves are being used. Go back inside, and watch key parts in slow motion. Go to real time, and watch one aspect only -- like throttle management.
2. Talk to people when you die Can't recommend this one enough, though it only really applies when you run into a respected player. Send a PM with a <S>, and ask where you went wrong. Sometimes you'll get real pearls of wisdom, or guys may open up whole areas for you to work on. (SlapShot did this for me a couple years ago after repeated furball deaths to him and some other BKs off a carrier. I was amazed that he kept getting inside me on loops and turns, so he asked how much I adjusted the throttle in a fight....new concepts!)
3. Specifically go to "good guys" with specific problems. Not that long ago I got really frustrated with how easily I was stalling, at the worst times of a fight. I wasn't exactly sure what was going on, so I mentioned the problem I was having to Batfink. We set up a time to duel, but by the time we met he had thought about it and was betting I wasn't paying enough attention to my angle of attack and the buffet cues. He was right, and from then on I've known what I was doing wrong when it happened, and I could work on it myself.
