The other problem with 180 point Ar234s is that a nice, well aimed Lancaster strike with 42,000lbs of bombs will get you .26 perk points on landing. That's what happened to me.
Took an Il-2 out and leveled a VH and got 4.5 bomber perks.
Level bombers can't get you any real perks without shooting down fighters. And at that point they're just, well, fighters.
BTW, the 370mph of ladden Ar234s is hardly uninterceptable. There are many free fighters than can chase them down.
