$1270 to save 1/2 lb at the rim?

That said, there's nothing wrong with someone spending money on light bike parts because they like having a light bike. Everyone doesn't have the same priorities. I see plenty of beer bellies on expensive race bikes.

Are you having them take apart and rebuild around the new rim? You would probably be better off having a new wheelset built and selling the old set assuming they are in good shape still

The answer would still be no. The question is at what monetary price is it worth it? That answer is different for every person. The OP has to answer that question on his own. If it is worth it to him, then he should get them. My opinion, or yours should not matter at all.

I can get Light clinchers, Sapim spokes and Mack hubs built locally for $870.
Claimed weight is 1357 grams.
This would save 253 grams or just under 9 oz rotational weight, most of that at the rim.
Tubulars have been ruled out for a variety of reasons including the fact that they don't make the tires I like, Vittoria Rubino G+ Speed, in tubular flavor. The next best tubular tire is the Corsa G+ Speed but the tubular flavor is 50 grams heavier than the Rubino + tubes. The Corsa tubs are 23 mm only and I run 25's. The Corsa tubs are insanely expensive.
Anyway, $1270 to save 7.9 oz is a different equation than $870 to save 9 oz.
The discussion here has been great and I really appreciate it. It still isn't compelling enough for me to start clicking a bunch of "Submit order" buttons but the input has been great nonetheless.

I love the completely random and arbitrary numbers you selected.
It's diabolical to think that you can train, lose weight, AND have better technical performance all at the same time, right?

Don't worry. People advocating for a specific FTP for a particular aspect of technical performance probably don't know what FTP is, period.

Depends on what else you want. In my grand scheme of things a power meter of some sort is my next "luxury" purchase. Garmin Vector 3's or whatever is out when I decide to open my wallet.

If saving weight is the only goal, you can do it much cheaper. I have a couple of pairs of wheels I build using components from bikehubstore.com that weigh 1285 grams. I used their lightest hubs with Kinlin XR-200 rims, 20 Sapim Laser spokes in the front and 24 spokes in the rear with Lasers on the left and Sapim Race spokes on the right. The fronts are laced radial and the rears are 8x16 laced radial left, 3x right. I'm 170# and they've held up fine on crappy New England roads. Oh, yeah, they cost under $250/pair to build! Even if you add $100/pair to have them built, they're still a bargain.

Saavedra Turbo. Also sold as Wheelsmith Turbo. Long out of production and very possibly all used up and gone. Very low production item to start with. But still lighter than any clincher rim mentioned here. I built a 32 as a 16 spoke front, one cross, and did around 10k miles while weighing 185# before the brake track got too thin to trust. Front wheel was just over 500grams. Titanium spokes. Some kind of light hub, not nearly so light as what can be had now.
Price? The rim was free because no one trusted it. Felt fine to me downhill at 100kph.

'Fine' is not the word of choice to describe how one feels on a bike at 100kmh. You start clenching your ring at half that speed...
A word about light hubs - folks shouldn't really count them as rotating mass. Sure, they rotate, but doubling the weight of your hubs will do stuff-all next to doubling the weight of your rims.
And light hubs come with drawbacks, particularly for all the folks using Shimano cassette splines - making them out of aluminum (without the steel strips a couple of companies use) is an example of a product designed to be sold rather than used. And don't get me started on the unserviceabilty, and poxy sealing of most cartridge bearings...
The industry standard of merely quoting whole wheel weights is bogus; it's of interest only to weight weenies. Nothing wrong with that per se, but I want to know how much the damn rims weigh too.

I wouldn't spend money on that. But, I did spend $600-700 on some Mavic UST's (comes with tires) and that is the best money I've ever spent on a bike. Smoother, lighter, faster and just generally a great feel.

Keep in mind that this is a "fixed gear road bike." It has a fixed gear drivetrain but is ridden on the road like any road bike. The rear hub will not have a freewheel but even so, track hubs and track components in general are typically not light. Anyway, I'm going to save about 1/2 pound and cost will be a little over $800.
Light Bicycle 35 mm deep carbon rims have already been ordered.
Hubs will be Mack Superlight front and rear. The 8mm bolt-on is slick. They come with an aluminum track lockring but this will be replaced with Dura Ace steel for street use
The plan is to have ProWheelBuilder.com build them with Sapim Lasers and aluminum nipples.
Weight should be sub 1400 grams with much of the weight savings at the rim for faster acceleration and easier climbing with a 48x16 gear. A slightly taller cross section wheel should give a little aero boost as well.

I wouldn't spend that much on a whole wheelset, so I'm not an opinion to consider.
That being said,
Will you want to ride the bike more?
--Would you feel better when you do ride it?
Then perhaps it'll be worth it. Certainly would be purty, and sometimes that's worth the $.
