Thats funny. Anyone with a serious reply that contains some useful information?
Just havin' some fun.
UST tires weigh a lot because of the amount of material in them. Remember that UST is just Mavic's proprietary tubeless brand and was originally designed to run w/out sealant. Since most people running tubeless want the benefits of sealant (even in UST tires), more manufacturers are coming out with tubeless designs, though mostly designed to work with sealant, so much lighter than UST. Since you said you don't want 'tubeless ready', do you only want certified UST (licensed by Mavic to have 'UST' printed on them)?
Mavic has done a fantastic job of marketing to get people to think that UST is the only 'real' tubeless tire... for a while it was, but many are catching up. I ride regular tires tubeless
and it works incredibly well for me, but ain't for everyone (obviously).
I think UST will have a hard time in the 29er platform because they are ridiculously heavy. They may even have a hard time competing with 'tubeless ready' tires on 26" because of the advent of sealant and the weight factor.
There aren't too many UST 29er tires to start with, and I don't know of one that is under about 750g. Heck, even 26" UST tires w/some tread on them push 900(+)g!!
I think only Geax, Michelin, and Hutchinson are licensed for UST and AFAIK Geax is the only mfr to actually make and market them... about four models. So, pick the lightest out of those... not a hard choice, I think you're looking at a Barro Race, which is a 2.0 XC tire w/out a ton of tread, and still weighs in at 740g (claimed).
