My take, for what it's worth....
First you have to "define" what a "pick" is. Picking to me is swooping in and popping someone who is already engaged in a fight. Now in a furball this is a "given" your doing it, they are doing it, it's what a furball is all about. It's what you expect to happen, the fun of the furball is to use your SA to survive as long as you can killing as many as you can be fore you finally get picked.
When fighting 1 vs 1, or 1 vs 2 then a pick is one step up from a HO. It still takes a bit of skill to time your pick right, but to me it is still a pretty classless move. Some people are saying that in a pony, or Dora that's the only way to fly those birds, well they are wrong. You can BnZ with them very well in a 1 on 1, or 1 on 2 situation. Yes and the "smart" pilot will will extend, or get out of dodge once he feels he has lost his advantages. That is "E" fighting and using the strengths of your ride. But blowing through a 2 on 1 for a cheap kill, thats just a dweeb move.
