i suggest presenting this same question to the 29er forum at mtbr.com the guys over there are very into their 29ers.
i didn't look up the rim in question, but i think other factors are worth consideration...possibly more so than the rim.
1) have you investigated dishless wheels? the downside is hub price.
2) what style spoke?
3) what is your body weight? are you huge like maelstrom or gastro? super fast like dminor? or do you hardly ever ride like mx_599?
4) have you ever built a wheel before? if you haven't, i highly suggest you do. you will feel very good about your accomplishment.
i would not be surprised if by the time you choose your nipples, spokes, hubs, and rims you will no longer have saved money. but like i alluded to already, it is a great feeling to do it yourself even if you spend a bit more.
