RE: pse dream season x7
I don't think PSE currently makes anything that is comparable with the Katera or Guardian. I know the PSE X Force, despite all its speed, is not as smooth or shootable as the Hoyt or Bowtech top-of-the-line bows - IMO.
You really ought to shoot them, though; and see what feels right for you. Also, don't make your selection without shooting the new Bowtech General.
