I've got two pairs of ENVE wheels with the XC 29er rims, I like them a LOT, but I'm not in love with the price. If Light Bicycle rims are roughly analogous but for ~20% of the cost I'm likely to own a lot of them quite soon.
That said, I do really rate the Flo wheels I've had in the past.
I was going to go for the LBs based only on price but I like that FLO have actual test data on their rims so I'm now edging towards their product for the extra $200 odd. I'll only bother with a front for now.

Flo would be tubeless and rim brakes though...
