If I go for something like AL22 or He'd Belgium they should be strong enough for 24/20 with cx-ray? I'm at 67kg at the moment.

That would bring me in at 1.321kg for the wheelset including locking and nuts, not the front skewer though.

they should be fine provided they are built properly, tensioned, stress relieved etc.

i was building light(ish) wheelset for a ss bike few years ago, in 32f/32r it came to 1435g, they are overbuilt, but back then i thought it was a right thing to do, plus i wanted matching front and rear hubs. i've also built a 20 spoked front wheel (same cx-ray spokes) on a son dynohub - this one feels flexier out of saddle, but otherwise fine.

If you go for carbon rims there is a weight saving and an aero benefit

Hard to get both - Last time I looked I couldn't find cheap carbon clincher rims *in any depth* that were lighter than the best Al rims. For deep aero profile they're often heavier than average Al rims.

OK

28h rear and 24h front Mack hubs ordered. Ti bolts, stainless bearings. 260g for the pair but cost €300.

Thinking HED Belgium plus. 25mm wide, tubeless and 465g, sapim X ray spokes and aluminium nipples. It will be my first build that will use alloy nipples but I'm really wanting to keep the weight down.

Thanks everyone for helping, 500g from my wheelset should help.

looks like an optimal setup. only despite what they claim, the rim cross section doesn't seem to be designed properly for a tubeless setup; i would look at a rim that keeps the tyre seated when it is deflated (i.e. either has a ridge on the shoulders, or shoulders sloping down towards the brake track). i've used non retaining rims in the past and they cause unnecessary misery/faff.

Al33 rims seem to be good but even more expensive than HED Belgium rims

I have owned a pair of HED Belgium... they were very beautiful, but I can't really say that I did notice a difference with the cheap and cheerful DT 460 I use now...

35-40 pounds Vs 130-140 pounds per rim... that's a lot of money!

I rode for a while with a wheelbuilder who swore by Kinlin rims.   I have no experience, though.

Probably Malcolm...

They are as good as any other rim... a bit plain, as they come without logos or stickers. I do like the 279, they are very stiff and build well. Or the T31 if you like something a bit deeper
