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 $.

I did a FG conversion with an old CF frameset, and the bike came in close to 14 pounds(and it was nearly all spare parts).

I thought the whole 'rotational weight' thing was a myth and it's been busted years ago. I'm too lazy right now to dig up the information.
No I would not spend that much purely for weight reduction. At least I try not to.

so it's a (potentially) net $200 upgrade?
Why are you asking again?

I'll bet that thing flies. It looks like so much fun.
No, a bit over $800 for the wheels with an expected $200 recoup from selling the old wheels so $600-ish net. Sorry if I was unclear.
The Euro is going up so I ordered the hubs today.

This is not so. 31 mph is a slightly downhill race or even TT pace... Aerodynamics being the limiting factor, 62 mph was a relatively rare accomplishment without drafting motorized vehicles, but "fine" is a fine word to describe the feeling of security, riding a good racing bike with trued wheels and well glued tires on good road. Perhaps carbon's reputation for instantaneous unexpected failure contributes to fear for some of high speeds on a bike. Tubular blow-outs were/are not remotely common events, and especially on well-known roads, going as fast as possible down hills was always part of the fun.

I haven't done 61 mph. If Strava is to be believed I've hit about 55 mph coming down from Barlow Pass. Garmin says high 40s, Strava likes to reimagine your data. I passed a campground and two kids were looking at me like bikes don't normally go that fast. Felt fine. Great even.

But with CX-Rays, that same amount of metal is in a lovely little blade (they are just beautifully made) that not only shows any twist, but allows you to easily prevent it. And the forging process to create them makes them the strongest spoke on the market, even though they're almost floppy out of the box.
They are the bee's knees, and worth every cent.

I used to hang onto trucks, without a (compulsory in my country) helmet. But now that I have a few grey hairs, once I get up to 60-70kmh, I can't help thinking how bad I'd get messed up if I was to come off for some reason. At 100, I reckon I'd be packing my dacks. And I'm not an anxious type; I see people cowering in unfounded fear everywhere.

I haven't built any wheels with Lasers (I think the thinnest round spokes I've used were 1.6), and I'd be a bit nervous about trying to with low spoke counts and high tension... I'd want to do tape flags, and have the wheel securely fixed in a robust stand in order to push it side to side to detension spokes as they're adjusted. 1.5mm is stuff-all to resist twisting.
But with CX-Rays, that same amount of metal is in a lovely little blade (they are just beautifully made) that not only shows any twist, but allows you to easily prevent it. And the forging process to create them makes them the strongest spoke on the market, even though they're almost floppy out of the box.

I appreciate your recommendation. "Worth every cent" is spiritual food for me.
Do CX-Rays require a different spoke hole at the hub or can they be fitted to the same holes that would accept Lasers?

I had to build the rear wheel with a White Industries ENO eccentric hub, but the rest of it was just spare parts.

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

BTW, there's no reason that you couldn't use a freewheel on those hubs if you wan't to. White Industries makes one that's top notch.

Would you spend $1270 for new wheels to save 223 grams (7.87 oz) if all the weight savings were at the rim?
The new wheels would be exactly the same as the existing wheels except for much lighter rims. Assume for now that the hubs, spokes, nipples, tires and tubes are already as light as they can go.
The bike flies and I've no need for new wheels. This would be a luxury purchase.
Wheels would be built by ProWheelBuilder and come with 2 year warranty and lifetime 25% off crash replacement. I could probably sell the existing wheels for a couple hundred.
This is on a sub 16 lb bike.
