Russell v kontour

can anyone compare the two? Both rebuild your stock seat to make the "most amazing, fantastic, comfortable seat ever", or some such.

a lot of people have raved about Russell's seats but I've not seen anything about kontour, or how they may differ. Has anyone been able to experience both and have an opinion?

Never had a Russell but had a Kontour on a previous bike. They use a multi-layer fabric for the cover. The top layer is an open weave, seemed to be better on long rides. When I got mine all they offered was the cover, not really a custom seat.
