I have recently bought a B17 Titanium on my bike, its by far the comfiest saddle iv ever had and has been since it was first put on. I haven't needed a break in period, although I imagine it may still get better:)
Ton has a very valid point though, they are widely considered to be susceptible to the wet.
Proofride is not designed to make the saddle completely water proof.
Personally i plan to change the saddle on wet days, and i carry a plastic bag and string to put over it if I ever get caught in the rain.
If you can find a modern saddle that is comfy for you, great-get that.
I failed to find one though.
Since buying the B17 Titanium I've put a B17 Std on my 2nd bike and a B17 Std S on the GF's bike(it was buy one get one half price at halfords).
They are very heavy compared to modern saddles as well. Mine also squeaks something terrible;P
