Question:

Do you have enough weight over the front wheel? If your stem is quite short and/or stack high, and perhaps your saddle quite far back then you are looking at another possible cause of a twitchy front end when descending in windy conditions.

When I changed the stem on my Propel from 90mm to 110mm and moved the saddle forward a bit the bike became a lot less twitchy in general and less prone to crosswinds descending at high speed in particular.

If this is the root cause of the issue then a shallower front wheel won't help.
I would think so, I'm on a 100mm stem and have the saddle quite far forward. Also I weight about 92kg so have a bit weight on me. I do plan on lowering another 7.5mm in the coming weeks so will see if that makes any improvements

100mm stem sounds pretty good, but of course longer may be better on a 56+ frame (sorry don't know which bike you ride).

Fit is of course highly personal, but don't underestimate how a small shift in weight can affect bike handling and behaviour in tricky riding conditions.

Rim + tire profile would have a bigger impact on stability than 8mm depth change. External rim width 32mm seems like a good fit for 28c tire that measures 30mm.

Honestly I think wind stability is a premium feature that takes additional R&D, so unsurprisingly it's a gamble to order from FS or LB compared with established brands like Enve, Zipp, Bontrager.
+1 on this. I had the same problem with my Farsports wheelset (26mm width). It was a lot better when I got the 28mm width rims. But the biggest difference was when I bought my bontrager wheelset.

True! But to be honest, I'd rate the wr40 set I describe very close to my RSL51 bontrager wheelset in overall feel and characteristics. (yes those are deeper).

Don't know why but it's been really windy here lately so I think I'm just going to order a WR40 and hope it's better.
Would there be any other noticeable changes from the 10mm drop in height? wheel weight would be pretty much the same as I currently have so can't imagine I'd notice any other difference

Well I bit the bullet and ordered up a WR40 so will update this in a few weeks when I have the wheel fitted.
I do have a question though I was going to order up a front brake disc so I could swap the wheels over if I needed, the wheel will have a DT240 EXP hub. What lockring will I need to order to fix the centre lock disc to the hub? As the DT one I can see says it's for 15mm axles when I thought mine were 12mm
