I re-jigged, and went for the SP PV-8 on an Exal rim as Spa do a bundle with this and B+M lumotec front/rear lights for 240 all-in which is fucking good.
All reviews I saw of the SP hub were really good, it's just that it 'only' comes with a 2 years warranty instead of 5 like the SON I think.
Do it, SON hubs are awesome.
