For the MM IV GB, if your build pace is not too rapid, pick smaller simpler kits. Their 1/48 B-29 and B-17 would not be wise choices. But a couple of their older single engine/single seat fighters in 1:72 or 1:48 will work easily enough. Especially non NMF single color schemes.
I know there are a few in my stash I would love to build, but to do them as I want them to turn out, they are not wise choices.
