I say "A" but with a caveat. I think if anything is changed then it should be to the effect that flying a buff would increase immersion.
Make the manifold pressure increase if you increase prop pitch with a steady throttle,(like real life)
Make it possible to adjust mixture (like real life)
Make these things automatic if you don't want to fool with them.
Make the Buff, especially the 17, able to take a LOT more punishment.
I like the idea of the norden sight working like it did in WB, but I don't beleive that makeing bombs disperse like in real life would do much to enhance gameplay (from a buff crew's perspective anyway).
I think it would be ok to reduce the effectiveness of the guns down to 1k, no closer though unless the toughness was increased dramaticaly.
If these can't be implemented then leave it the way it is as far as I'm concerned.
I fly fighters more than buffs for the simple reason that landing a buff mission is almost impossible with the arena populated at over 100.
Getting fighter escorts is near impossible but my squad has done that. Even with escort, buff missions are not very succesfull as far as making it back to a landing.
There will always be this argument. In here, in WB and in WWIIOL when and if it ever gets going.
If you are patient in a fighter you will kill the buff. All it takes is the proper approach. If you don't want to have that patience, then don't bother. And don't whine about it either

'Nuff said.
