I still think you're level bombers are way off. The B-17 has no place here as it can't be balanced against Ju 88's. (see my last post for more analysis on this issue)
I did look at your earlier objection. I'm not ignoring it, but I think the B-17's are appropriate and OK. I want there to be B-25's, B-26's, and B-17's if at all possible because they were there. Half of them are B-25's, 1/4 are B-26's, and 1/4 are B-17's -- so 4 B-17's is all (which isn't a huge number).
I think it is balanced OK since B-25's take 3000 lbs, B-26's take 4000 lbs, and B-17's take 6000 lbs while the max loadout of the Ju 88 has 4400 lbs external (the 4x500 kg) and 2200 lbs internal (20x50 kg) for a total of 6600 lbs. That makes it like a B-17 in total load, although because of the difference in locations and types of ord, it is not as effective as the 6x1000 of the B-17, but still better than a B-26, as you get a B-26 loadout on external then an extra internal load that at least can be used for some mischief (although not very well at a town because the explosion pattern is too diffuse to take out more than 1 building in my testing). The Ju 88 is (at 12-15k) faster than the B-17, the same speed as the B-25, and only a little lower than the B-26. In survivability, the Ju 88 is better than the B-25 (50% of US bomber set) and worse than the B-27 and B-17 (together 50% of US bomber set). So, it is in all respects in the middle-ish range in things compared to the US set.
Also, do you really think you can fill 2 bomber squad's per side? Seemed to me that filling one was a challenge during Dnieper.
I am anticipating a registration for this that is 2x the registration for Dnieper. However, I have a question above on how to deal with player fluctuation during the event. I'll bring that topic back up again soon to get more discussion on it.
