How do you actually pick a comfortable saddle?

I pick the lightest and most pleasing to the eye. Then I put on the best shorts I can afford and go and ride on it.
Guess I must be lucky that the SLR type of saddle works for me!

LOL. Hate to admitt it but +1
I bought one of these for the fixed, based mainly on weight and looks.

Now its my all time favourate saddle. Like sitting on a walnut for the first 5 minutes of a ride, but after that its perfect. I spend much more time seated when riding fixed too, so something most be right. I read somewhere that its based on the flite, so maybe I should look into getting one of them at some point (that saddle^^ is no longer produced :( )
