I had a Romin (not the evo) - hated it.
The upward kick on the tail encouraged not only for me to sit forward on the narrow portion of the seat, but also forces your pelvis to tilt ever so slightly - putting even more pressure on that sensitive spot.
I switched to a Fizik Antares - much much happier. That said, everyone is different - I just prefer a flatter saddle where I can actually sit on my sit bones on the wider, rearward portion of the saddle, especially when climbing.
