I REALLY like the Romin, but I've broken 2 of them and my 170lb teammate broke maybe 4 between his road bike and track bike.
They develop cracks in the plastic in the middle of the saddle where the saddle bows under weight.
This was in 2011 and 2012. Maybe they have improved it since then.
I would definitely recommend that people try it. The good thing is that a specialized dealer will (or at least should) replace it over the counter if it cracks on you. That's how my teammate and I went through so many of them.
I eventually went to the Fizik Aliante which has a similar curve. My current saddle is the Selle Italia Max Flite Gel Flow. I like it better than the Aliante. It's nice and comfy for use on bumpy track or grinding hard in the saddle. But, this is after LOTS of trial and error.
