yes, I am a big fan too of positioning infront for an intercept, then crawling low & slow so the convoy arrives "overhead". I've had good successes regularly bypassing the lead escort by doing this. I make sure I stay well to the opposite side of the lead escort as I come in.
I might be a bit of a pyro, I love picking off tankers first hehe. Good tonnage and always a good chance of a fire show.
Nice work Khan - nothing like putting a big dent in a convoy!
