I haven't tried ramin yet. If I can find someone who carries them long enough, they're always out of stock.

A friend of mine tried a dozen though. He said they were very nice shafts, very straight, right out of the box. But after he stained 'em and put a couple dips of gasket lacquer on 'em, he said they went all kinds of crooked.
From what I've heard, chundoo (lodgepole pine) is better than ramin.
