I weigh 210 and have had not problems with my numerous Brooks saddles, 1 B17 and 3 Team Pros, one "Pre-Softened". Although they have gotten pretty wet, I have been fanatical about Proofiding so the leather itself has nevers soaked up any water that I could tell.

Froze, what is your basis for the statement that excess Proofide can over soften the leather. In my experience, contrary to popular belief, Proofide does not soften the saddle at all, nor is it designed to do so. I go through an extensive Proofide regimen when my saddles are new. Applying repeated applications with very gentle heat to soften the Proofide and encourge absorption. I repeat this every few months. I will admit that I have only been riding these saddles for 3 years, but so far they are still so hard the Team Pros feel and sound like wooden boards when I knock on them. I have noticed that the B17 is not as hard as the Team Pros but still quite firm.

Those of you new to Brooks saddles, you DO NOT want to soften the leather in any way. Softening the leather will cause it to loose its shape and eventually lead to failure. Many Brooks users will tell you that "breaking in" a Brooks saddle has less to do with the saddle than with "breaking in" your butt to be comfortable on the saddle.
