Hope Hoops

Thinking of buying some Hope hoops. Does anyone know why they seem to differ slightly from retailer to retailer, I noticed that Wiggle say "Mavic Open Pro rim and Sapim Sprint spokes ...Weight: Rear 915g"

Whereas Chain Reaction say "Weight: 925g (rear)... DT Swiss double butted spokes".

Winstanleys are different again "Spokes: ACI Stainless Steel Double Butted...Weight: Rear 915g".

Are these just old descriptions or do retailers customise the wheels ? Should I really be bothered about different spokes?
