I found another similar thread over in the Eyepieces, Barlows and Filters forum where Suzy decided to go with the Pentax XW. Is there an answer to this?!

I have two Planetary II TMB Eps. The 7mm and the 3.2mm. They are good EPs for the money.
When I say the Hyperions are superior that is really just my opinion. Also, they are excellent by my standards but certainly not as good as Tele Vue, Pentax or even the Vixens, but you you are upscaling in cost considerably there. I have done a heap of research on EPs over the past six months so am nowhere near an expert but the Hyperions work for me because they provide very sharp pictures over 80% of the field, have a wonderful 68 degree FOV and the focal length can be altered by the use of filters or finetuning rings to give you a higher magnifcation from the same eyepiece. It's just me being a bit superficial but the TMBs aren't very attractive while the Hyperions are big nasty buggers that feel nice and look good. They also provide fantastic eyerelief 20mm, superior to the TMBs (but the TMBs at 15mm ER are very comfortable too). I also like using 2" filters which the Hyperions allow for.
Hope this at least helps differentiating between TMBs and Hyperions at a superficial level.
