Not sure if the 117 was designed for the 1-12 twist 257s are if it is just a coincidence they perform in the Wby. and the Bob.
Back then it was the only 117 that would stabilize in the older twisted 257s.
A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
