G10 for me, it's a twitchy little bastard, very tricky under wep but I fly it with Gondolas and 30mm, and go hunting buffs at 30k. A few cruises at 35k across a prime realestate path will surely bag you a high flying and lazy B17. A little dive, a snapspray with those 3 cannon and some MG and it's toast.
Plus if you go down lower it keeps your E fighting habits up strong, you don't dare turn the plane with that setup.

If your in range, so is the enemy.
