Interesting thought. With the OS 4S 91 apparently being replaced by the 110 eventually, what do you think SPA will do when the 91 is no longer available new?

1. Stay with the 91 and find NOS NIB or find used engines
2. Approve the new OS 110 4S and allow piped 61 2S
3. Approve the new OS 110 4S and tell the 61 2S fans to take a hike
4. Reduce the CI to the $340 OS 81 4S.
5. Go back to Mickey’s original plan of 61 2S.
