I've personally never had issues finding bottom or vers guys. Maybe it's just who I find attractive. The one time I was interested in someone who advertised as a top, he said he was willing to bottom for 2k. I'm inclined to believe that so called total tops will bottom if the money is right.
The "American" boys who got to Prague usually keep their US porn names so I'm guessing he'll do the same. I have no idea of the scene pairings but he has been posting pictures on his twitter.
