And the new Xstreams have a higher bottom bracket, which can't help but make a difference in how they handle each seat, so I don't think comparisons between seats on the old style Xstreams are valid for new ones.

I took special notice of the bottom bracket height/seat height change because that's what made the Hoagie, and even my Euromesh, which I borrowed from the Corsa, not work for me on my old style Xstream. That was why I traded for a Sling Mesh seat. Small changes in riding position can make a big difference in comfort for some of us.

I don't know if it sits higher. It probably does, at least a little. But that's not why I switched to it. Like all mesh seats, it's more suitable for sitting more upright. A Hoagie (or Euromesh, carbon, or any other Euro style seat, for that matter) only works for me if I can use it really reclined. Really reclined never worked well for me on the Xstream because it left me with too open a body position. With the higher bottom bracket on the new Xstreams, that might not be the case, but on mine, I wanted a more upright seating position to close my body position, so I switched to a Sling Mesh.
 
There are obviously people who can tolerate a really open body position (laid straight out, not bent at the waist), but I'm plainly not one of them. That seems to be another of those individual things that each of us has to figure out for ourself.
