I've got a Russell and I love it. The only thing I wish I could get with it is a heated insert (like the Corbin and Rich's have...yeah yeah, I'm a wuss). Unfortunately, when I asked the good folk at Russell (before I bought my saddle), they told me that they'd had some requests for this, but hadn't gotten around to figuring out how to do it.
I got a heat insert installed by Russell. All you have to do is buy one from Travelcade and sent it with your seat to Russell. You mark a place on the bottom for the hole to extend a wire and they build the pad into your seat.
