"debating the fin can, I'm a balsa purist, lol."

That is why I made sure to include a fin template!

"Any hope for the PNC-50 used on the USSF Fireflash and others?"

I have a PNC-50SP nose cone from an old Estes Argosy rocket I bought from someone else several years ago. It looks like it is a nose cone from the Black Brant kit (PNC-50BB/PNC-50V) but they added a cockpit area to it.

I'll put that on my list. I have a few other projects in the works that I will post in the future ahead of this nose cone.
