I voted for a combination. I rarely go for smooth pipes, I prefer sandblast and rustication. BUT it depends on the blast or the rustication. This blast for example is what I desire: http://s58.radikal.ru/i159/0906/65/562f0906f2eb.jpg
none of that lightly blasted crap where it looks like someone blew pixie dust on it. And as far as rustication goes I'm content with a variation of different finishes.
