How big (or small) are you fellas? My bike came with a 143 Romin and I've been giving serious thought to swapping to a Romin EVO. I've read many times where Romin users have gone from a 143 to a 155 and loved it. I know everyone is different but I'm a med/large fella at 6' 170lbs....

I guess I could go get measured but figuring I won't be buying a saddle at a LBS, I'd feel bad wasting their time.
