Would do a 29-31 cm build if I was your height. Someone like me who's a little under 6' would do better with a 32-35 cm build.
Just be patient,it takes a lot of time and work to get one of these helms together and looking nice. The Hayabusa is some extra pain in that department. I wouldn't recommend it for a first helm if you've never pepped anything before.
We warn folks for double posting BTW. Lots of folks read all the new topics and there's sure to be somebody who'll post some help without the topic needing a bump. Be sure to read through the stickies if you haven't.
