This is a good conversation for me, because I'm also thinking about this now.

I was thinking about getting both boom and spi pole from same section, because I was hoping to get it anodized (I need them black <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />) and here in Finland it seems that I must have at least 6 meters section to be anodized. This would propably mean compromising on the boom (i.e. 40x2 mm or something).

I got the idea of black sections one evening and now I'm pretty much obsessed about it... Let's face it, carbon is fun only because it's black <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
