Thanks guys!
I'm thoroughly familiar with Golden Wings, since I developed and used it extensively from the day it was released until I dropped out of the hobby a couple years ago.
I'm also very familiar with the Cal Classics material, as I used it in FS1954. I just backdated their AI scheme by replacing the turboprops with propliners.
My biggest objection to my old FS1954 was the presence of the Interstate Highways, and I was hoping to get rid of them this time around. A stock GW rolls the era back to around 1940, which is a bit early for FS1954, especially since I already have a GW that's set at just a couple years earlier than that. (I set it back a little more by removing many of the big Army Air Force bases that were constructed in the 1939-1941 base building boom, which GW doesn't delete.)
I'd hoped that Silver Wings would delete the Interstates, because otherwise it seems like the optimal basis for a new FS1954. But with the Interstates present it would look more like the early sixties than the early fifties.
Hmmm... base FS54 on GW and have it look a bit too early (and a bit too much like my existing GW), or base it on SW and have it look a little more modern than it should. That would still be less modern looking than what I had before.
I suppose there's a way to mix and match and take the road structure from GW and put it into SW, but I don't think I have that much motivation! I killed the fun and drove myself out of the hobby by letting it become too much like work and not at all like play; I don't want to set myself up for another case of FS burnout!
Maybe I'll just go with Classic Wings straight from the box, and add the same stuff to it that I had before. That won't be an optimal FS1954, but it will be an improvement over what I had on my previous confuter.
