Wheelbuilding / Wheel Building / Wheel build help

Can anyone critique this selection of parts for a wheel build? And offer suggestions of changes.

For: gravel/road/light touring
Requirements: QR 100/130, rim, dyno, cheap-ish, for 35-42c tyres, black rims

1. SP PV-8 32h
   
2. Novatec F172sb 32h rear
   
3. Kinlin XR22t (any reason to go for XR26?)
   
4. ACI DB spokes/brass nips, I've used these before for several wheelbuilds and they've been fine
   
   

This comes in <£200 and ~1950g, which I'm happy with for a strong, dyno wheelset, certainly better than the stock wheels on my Tricross.

Cheers!
