old t&g pine 1x4s over floor joists, chewed up, abused, patched in, etc. Don’t want to try to save it. Need all head space can muster in upstairs 1 1/2 story. Luan over the t&g then old salvaged oak t&g strips, maybe 1 1/2inch wide by probably 5/16 inch thick. Question: should I use ringshank nails or screws in placing the luan to the pine t&g? I was concerned over the screws working loose over time and causing a problem?

Can only give you one case history. Used 6d ring shank on my house 32 years ago to attach edge spaced 5/8 ply or particle board over t&g 2x5 car deck with 15# felt interlayer.
Nary a squeak until last year, when we had a 6.3? earthquake. There are about 10 separate area that have since started to squeak. I thing screws would have worked better, but 30 years ago screw were lots more expensive than now.
How about narrow crown staples? That's what'
s typically used around here to hold down luan.

thanks boss, I had already screwed down the luan. Just more of a leveler than putting felt paper down on top of the t&g pine which now becomes the subfloor. It was thought after the fact that the screws came to haunt me. So I added some ringshank nails to the hodgepodge. Bloody rank amateurs anyhow. I'm planning on using part of the luan covered floor as a bathroom with ceramic tile. You think I should use roofing felt under the tile and the oak strips both?
luan isn't a good idea for a tile substrate, not strong enough- use 3/4" exterior grade ply subfloor, then install backerboard before tiling. Don't use roofing felt under the tile. If you're concerned about waterproofing, use a trowel-on liquid membrane between the underlayment and the tiles.
