The plated barrels cost less

Yep, I fat fingered that. Plated barrels cost MORE, but it's usually worth it.

I am thinking of using Tubbs Final Finish to smooth out what ever type of barrel I get.

DON'T use any of the abrasive finishes or lapping systems on a hard chrome bore.
The hard chrome CANNOT be broken in because the chrome is so hard, the standard break in systems don't work.
Also, the abrasive final finish systems are for carbon or stainless steel bores ONLY. They will have not good effect on a chrome bore, and would likely cause damage to the coating.

That's one other advantage of a hard chrome barrel.
There's no "break in" necessary OR POSSIBLE.
You simple take it out of the box and start shooting it.
