Junky is 100% correct IMO. Remember SKyyr? He won many duels, lost some too, but sure surprised an awful lot of people, myself included, I went 1-1 with him, then he won the next 3 in a row, all because he had the merge in this game down pat. I mean absolutely needle sharp precision with how to get on top in various aircraft in the merge - once people started to figure this out with him, and just matched his move in the merge, then it became a pretty even contest again with average joes like me vs someone with a perfect merge much of the time. Just my opinion.
Anyhow, there is one mistake I see guys often make when they are all about picking this stuff up - they don't pull hard enough. I realize there are times when pulling too hard is a bad thing and wastes E, but once you commit to using your turn performance - use it, ALL of it. So many times I see that, guys make break turns, or go for a shot, but only 1/2 bellybutton (I actually typed bellybutton) it, instead of reefing all the way to black out or stall/etc and just riding that knife edge of performance. Again, just my opinion, but I observe this every time I fly, and think to myself "all he had to do was pull harder and he would have got the shot/not died/etc/etc." So, Mikev, if you're in a Spit especially, if you go for a turn fight, TURN, as hard as you can if it'll get you that shot or make that evasion successful. The trick I guess is knowing when to conserve a bit of E and not yank if you don't have to, but IMO, by defaulting to pulling hard you'll be better off and get more shots/evasions and that instinct/knowledge of when to ease off will come in time on its own.
I only say this as I've watched some films recently and that's the immediate thing I see, not pulling hard enough when committing to a turn for whatever reason in whatever dimension.
