I don't like the PLASTIC black tips, but I DO like an actual ebony wooden tip atop a nice stock. Adds contrast. My .257 Roberts that I had built on a Turkish Mauser action sports a rosewood tip which I like (would have preferred ebony but it cost more).
I have to admit though, whilst I'm all about modern guns on handguns, I'm completely opposite and like classic style rifles. If I ever had the time and money I'd love to have one done up with a Niedner-style buttplate, steel grip-cap, inset slight swivels, shadow-line cheek-piece, and a nice ebony tip on the stock. Hand-cut wrap-around checkering too. That setup in something like 7x57 or 6.5x55 is pretty much my dream rifle.
