Hi Furbs,
The thread became five pages long already so please forgive if somebody has posted the solution/ comment already.
Trees, well don't sit around, grab an axe... sorry it is not mine, but it is hilarious... in a way.
Trees, why on earth do YOU have so many trees in YOUR settings!

You have no sig with your rig so I presume you run with two GTX580 and decided to sacrifice some of your 150Fps (obviously with mirrors on) to get some trees in
We fly on the same server so on my settings, there are no trees

Ecologically embarassing

but, it does the trick.
The same discussion took place when the clouds model came after one IL2FB patch. The guys who had realistic and many clouds were trying to hide inside and were screaming at the "cheaters" who were able to see and shoot through clouds
Until they realised they had to better take them off just as everybody else....
So yes, tactic! maybe but with limited strategic value. You can fix it and that is the end of it.
Of course it would be nicer to have damage models for trees but we have way too many trees and they are an fps killer (for this generation of graphics cards).
My 2cts.
