Wow, you know your taking too long to reply when 6 other posts appear lol
And back with the program:
I have read on a number of sites that comfort comes from springs. Most were offering rails made from exotic flexible materials, costing enough to make any plastic bounce lol
I think taking the springs off is a great upgrade for a racer saddle. It's lighter and more aerodynamic, while becoming easier to make. Then you can spend time making them from flexible materials and covering them with something different each year.
A lot of us don't want a saddle. We want a seat. Like a motorcycle. This is when seats with springs start to make sense. Mine's coils springs, and there is no way I'm getting off it to pedal. Unless I'm bumping up or down a curb, or in the process of falling off, I'm seated. I have no suspension except the seat and my 30psi 2.15" tyres on suitably wide rims. I have never stood up because of a bad surface. I find myself slowing down because the bike is rattling to bits and the handlebars are bouncing about, but my weight stays mostly on the seat.
Leather has a nice wicking action and this taught unsupported span will take on your shape over time. So comfort improves. As if becoming tailor made.
I have just about settled on buying a velo branded one from ebay. There the brooks is about 100 sheets and the velo 60. My Ventura gel seat was just 10, but it's ok. My cycle hobby is one I expect to pay for it's self in fuel savings. Then it gets treated lol Couple more weeks now
