Has anyone done much research on which variant was most produced? Or rather which one would make the most sense in getting in to AH?
I don't have any legit sources on the He111, but from glancing at the variants I'd like to think the H-6 and/or H-10 would be the most logical because it has a 20mm in the rear ventral position and can carry 4400 lbs of ord. Armor was increased as well as engine performance (270mph at 19k). The H-6 was more of a torpedo bomber with the 20mm in the nose, and the H-10 was a typical level bomber with the 20mm in the rear ventral instead. The rest of the plane used MG 15 (.30 cal) or MG 131 (13mm) MG's for defense.
I've tried, but like you I don't have any legitimate Heinkel sources.
The problem with the H-6, as you describe it, is that it would be useless for a Battle of Britain setting, which is often cited as the primary draw of the He111, i.e. "You can't do a proper BoB without the He111."
Honestly, we probably need two versions, an early version for Spanish Civil War, Poland, Norway, France & the low countries and Britain and then a later version for the rest of the war.
