What Storch said might be a good idea. Another good idea thats floated around lately came from VF-27's Erg. His suggestion is to have less models per setup. I like his suggestion, I may not know what his views are on it, but to me, it would allow more setups.
If you concentrated on a maximum of two fighter types for each side when possible on these setups might become more interesting, plus it would give you CM's more options. The 7 model on this side 6 on the other have been done time after time, and ideas are running out for new setups.
How about a setup with say P-47 D11's Hurri II's or a applicable spit model against the 109F, OR ,,,,NOT AND ,,G-2, and the FW-190A5.
You could use the same map later with later models , or dfferent models. Same map but different setup. It would work in PTO's, ETO's, MTO's, and Eastern Front.
Justa thought
