I am refinishing my stairs.  Because my 125-year-old newel posts and handrail had some sections that had been painted white, I decided to strip everything.  I am now trying to decide the best finish for these four beautiful newel posts and handrail.  The wood handrail has such a lovely tight smooth grain.  The oak on the four newel posts is also quite lovely.  Help?  What is the best way to finish this project?
