I had been riding the Romin Pro (143) for several months and loved it -- till the shell cracked. I was able to get a warranty replacement from my LBS, and the shop owner gave me the option to go with the EVO. I always thought the nose on the Romin just a tad too wide, and I often caught my shorts on the nose, so the slightly narrower drop-saddle appealed to me as well.
The extra padding was actually my main concern -- I didn't really feel like I needed it, as I liked the original Romin, and who needs extra weight?
The Romin EVO has a very noticeable amount of padding vs the rock-hard original. In addition, the shell of the EVO flexes a lot more than the original -- I'm hoping that the flexibility will mean it isn't as brittle and won't break.
After putting the EVO pro through a couple hard rides, I have to say that I'm very pleased. I still don't know if the extra padding is necessary, but the more flexible shell makes for a very smooth-feeling ride while still maintaining a very solid feeling of connection to the bike. I'd say that I feel even more connected, since road bumps and vibrations don't bounce me around as much.
This saddle works for me both right out on the nose during hard efforts and sitting farther back. For the way I ride, it's a good fit. We'll see if it lasts longer than the original Romin.
