Your local Specialized shop should offer a 30-day return period on a saddle purchase, so I wouldn't be concerned about being out the $250. I developed the same issue as you and it was over time as well. Moving over to a) a thinly-padded saddle that is b) wide enough that I could firmly plant my ass bones with c) a cut-out solved my problems. Even on 7 hour long day, when my legs were fried and I was sitting pretty heavy (less weight on the pedals, more on the ass, if you know what I mean), I didn't experience any issues. For me, it happened to be a Toupe 155. I do recall that, between the Toupe and the Romin, they recommended one more for aggressive positioning like yours, but I can't recall which.
