I also don't care for "The Rift." The first thing I think of when I hear that term is a rift in a relationship, which is not what we want, at all.
I don't mind "Bits O' Legionnaire Business," but I do think long ago and relatively obscure terms might be off-putting to new readers. One has to be aware of what those "bits" were (letting fans come up with their own characters, usually) to understand the reference.
Also, I really dislike "More Action/Adventure Comics." It sounds like an ambiguous reference to both the Legion's past and non-Legion comics. (Not all of the comics discussed may qualify as "action/adventure," at that.) Sometimes the best name for something is the simplest and most direct: "General Comic Books," in this case, says it all.
But that's just my opinion. Scott and Gary can call the forums Eenie, Meenie, Minie and Moe (and Larry and Curly) for all I mind.
