I have dp18s on my Kilo and love them. I was also torn between Weinmann and Velocity at first but even though I ride on a daily basis, I don't really need anything more than what I've got.
Origin 8 'Tessa' rims are rebranded Weinmanns and their track hubs are rebranded Formulas.
And yeah...we all buy things for aesthetic reasons (bike-related and otherwise).
