I vote use what works for you. I bought a Fizik Vitesse when I assume they were very new. At the time it was still being marketed as unisex and for road. Coming from the terrible Titec saddle that my bike came with anything was better.
On my roadie I have a white/pink Fizik Vitesse and plan to get a black one for the old Sugar I have my eye on.
Working in the industry and being more intimately involved with every friggin part, eh hem, I have noticed that the big differences start to appear when you really get into specialized riding. Sliding off the back, grabbing the nose with your thighs, grabbing the nose with your hands for crazy dirt jumps tricks (my dream) is when it makes a difference. I rode and raced on that Vitesse and I feel it allowed me to be very dynamic on my bike.
I say if it works for your needs and it's comfortable go for it. No saddle that causes discomfort is worth it. I'm flabbergasted by those of you who can rock a cut out. Can't tell you how many times folks have tried to sell me those. I have uh, fluffy, girl parts and those seem to pinch my "junk" as it were.
BTW I hate WTB saddles. I think they have a lot of awesome designs, and I rode one I really liked, but that turned down nose grosses me out. It looks like a bird beak leaving my crotchel area and I just can't deal with that.
