I have made a decision! (well...kind of)
After pouring over countless youtube videos, looking up PDGA approval specs for every single mold recommended here, and reading through individual DGCR threads for most of them, I have arrived at a semi-official list of competitors.
1. Stags+Getaway. They aren't officially out of the bag yet. There's always the chance that I keep throwing Stags as my workhorse fairway mold, and then continue to slide a single Getaway into the bag as a gap-filler between Felons and Stags.
2. Pipeline. I've got a heavy SP Pipeline and light PL Pipeline in transit and arriving Monday or Tuesday next week. The PL Pipeline looks like a an exact replica of a Stag flight. Really, the test will be to see if a SP Pipeline adds just enough extra stability to allow me to pull that gap-filling Getaway out of the bag. If I can swap two Pipelines in and take three discs out (across two molds), then I think we have a winner.
3. Undertaker. These flew under the radar. I read back through all the recommendations one more time, and noticed that I missed a reference to the Undertaker. And that jogged my memory, because I remember wanting to try them before. While listed as a Speed 9 (slightly worrisome), it seems that quite a few people think they are really a tick slower than that. Lightweight ESP Undys are out of stock everywhere, but I did manage to snag a heavy Elite Z and mid-weight Big Z.
4. TL/TL3. The TL was really nice. I would have liked to see more distance out of it, and the limited plastic options aren't ideal. I will keep this mold on the back burner for now. If neither the Pipeline or Undertaker work out, then I will probably keep my eyes open for a run of lightweight G* TL3 to see how those compare to the Champs that I already borrowed from a buddy.
And that's it! Thanks for everyone's recommendations. I really did look into all of them, but was able to whittle down the list via additional research. Not saying I won't consider anything else at this point...but I would probably need to receive a free tester disc in the mail if you want me to consider an additional mold
