Are you at or approaching 200#'s? I am 205, and tried a sprung Brooks B67. No workie for me, too much bounce.
I have had a B17, a C17 and a C19.
I have found that the Cambium saddles are as comfortable as the leather ones, and have a good amount of give. I like the C19 imperial the best, but YMMV of course.
So leather or rubber, sprung or unsprung, regular or imperial.... lots of choices.
Pro Tip: Buy at REI and you can return it within one year if the saddle doesn't work for you. Alas, you just missed the 20% off sale!
