I'm in the process of doing the same thing now myself. How are your
knees holding up?

I'm not using nails I'm using screws. I have a box of 2500 #8 x 2-1/2
that I got from McFeely's and I'm putting them about every 6". It
might be a little overkill but I don't like these damn squeaks.

Good luck.

These RS nails are the underlayment type and thin if you ask me. Plus I'm
going through subfloor into joists.
