What kind of bike is the Utopia? And what width is the Evoke that came with it? Are you uncomfortable while riding, or just sore afterwards?

I tried an Evoke WSD last year. Long story, but even though it's meant for a more upright position I tried it on my road bike. I was able to do long rides on it, but was generally not comfortable and felt bruised afterwards. The topography was wrong, and also I think the nose was too wide. I am planning to try it on my mountain bike one of these days.

Bontrager offers a 30-day guarantee so you could try a WSD Evoke at no risk. You should be measured first if you don't already know your sit bone width. There's a good chance a stock men's saddle is too narrow for you.

If you bought the Butterfly from a source that offers a comfort guarantee, I'd say it's worth trying that, too.
