I really like the Hyperions, especially with the longer focal length scopes like yours. I do find them a little soft at higher powers. They are fine for general purpose viewing, but all the Televue types and the Pentax XW's are sharper and noticeably so, especially on planets. I also noticed that smaller DSOs, e.g. Stephan's Quintet, were easier with T6's and Radians than the Hyperion. Finally, I split Sirius a few times this year with a TV 11mm plossl and my C14. I was unable to make the split with a 12mm Radian, an 11T6 or a 13 Hyperion. This was true on three separate occasions.
All this to say, I've found Hyperions are great for general purpose viewing, but there are better eyepieces for specialized observing.
