I know that black was stock but when some people put in new wood they like to see nice new wood.
I will be using oil base polyurethane, clear rubbed on satin. No shine or gloss when dry so it looks like natural wood and doesn't show scratches like gloss. Soaks in really deep and building up 4-5 coats seals well. When it gets worn or dirty a quick sanding with 220 and wipe on another coat.
For strength and durability, fir is better than pine.
