I tried the Blackwell Flow. It was nice and narrow in the nose, cushy without being poofy or too big, the cut out was not irritating- but the seat was just a teeny bit too narrow for me. I rode it a month, though, up to about 45 miles, but then switched it out for the Vitesse when I had a 200k. I wish BF would try it- it's really a mens saddle, though Blackwell Research says it's their saddle that women like best.
Right now I'm trying the 2005 Zero X. It's very firm. I'm not sure yet...
