Joking aside, I don't think there is a "secret". Better quality foam than stock in multiple densities. I had James build me one for my 950 and I'm happy with it but I don't think they have a monopoly on comfort, there are plenty of aftermarket seats that are perhaps more comfortable for road work. I bought a used Russell Day Long seat for the 950, it was more comfortable than the Renazco (in my opinion) but the winged design while great for pavement, definitely impeded forward/backwards motion when riding off-road.
I'd love a Russell Day Long for long street tours (400-700+ mile days) and use the Renazco for dirty rides of 200 or less miles.
