Looking at the shape of the Power Arc compared to the Romin, it doesn't seem like it should be positioned any further forward. Has anyone else run into this, and how did you address it? Am I taking crazy pills or missing something obvious here?
Unfortunately it is exactly what it looks like - different saddles have different rail position relative to the seating position, even when they come from the same manufacturer. This is especially noticeable with the new stub-nose saddles, they frequently position the rider further forward compared to a more traditional saddle.
You can either try and see if slightly less setback will work for you (perhaps you weren't actually sitting that far back on the Romin), try to find a seat post with more setback, or you will need to look for a different saddle unfortunately.
