Also have a look at the options from JRA they do a number of factory options and a custom wheelbuild option, which you can obviously play around with. They offer a 1415gm wheelset by Stans at £369 which I was close to buying.
I eventually went for some hand built wheels from Superstar. Superleggera Titanium rear hub, superfast front hub ,CX-Ray Sapim blade spokes, Stans Alpine rims all for £395 and weigh approx 1370gms. I’ve had them nearly a year (not used in winter) and brilliant so far, rear hub sounds lovely and is instant engagement.
Some people slate the wheelbuilding at Superstar, but my experience has been only positive, plus they come with a 2 year guarantee.
