Finding the Right Saddle

Maybe it's just me, but the search for the perfect saddle is akin to the search for for the Holy Grail.  Even if I am saddle sore and numbness free I wonder if there is not another saddle out there that would offer me additional comfort (especially on those 5 hour rides). I did find this article on finding the right saddle to offer some decent guidance on what to look for in my next saddle.  I think this off-season is going to be a good time to try some new offerings and really find the right saddle for me.  If you have any recommendations out there, please let me know.
