I never consider it a disadvantage to being lower, unless there are 3+ above. It's all about timing and predicting flight paths relative to yours - experience.
Now if I'm up against a winged pair or trio, I will be flexible in my plans, always engaging (and often using one to set up another that thinks I'm the one being set up) what I consider to be the bigegst threat. If you work it right, you can also pair them up and basicaly make them do what you want.
And then at least one, hopefully 2 or all 3 will experience FAIL and end up in tower.
The coordinated wings are actually easier to deal with that the one or two random ones coming in. It's important you're constantly aware of what's where and what may be coming in.
If you want to get better at this, I'd suggest you use a base not under attack to up your ride and head for the mid-point between the two engaged bases. You can often lure a few away from the lemming trail. Just make sure you don't get too tangled up too close to the trail for those random gangmonkeys to cruise over for a pick.
I've made a bazillion films in a variety of planes in these situations... all lost in the great hd crash of '11
I've proabbly made a few more since I came back... I might be bothered to look around for a few, but I hate the free hosting sites... PITAs.
In any case, keep practicing, always keep an eye and engage the biggest threat, even if you have to think ahead somewhat and manipulate the weaker of the pack to set the hook another.
Expect to die... a lot... but you will get better.
You could even ask 2 or 3 others to go to the DA with you and work on that specific situation, over and over... I've done it, under different set ups as well.
It does help to have some room under you to work it... once you're trapped on the deck, it's a different kind of fight, but still doable.
