Any users out there have anything to say about these eyepieces?

I have used the 41mm Pan, it is nice but not as nice as a 31mm Nagler. Very wide FOV but it is just not quite as sharpe.
Have not used the other two.

I have compared the UO 40mm Mk 70 and the 40mm pentax XL in my 12.5 f/6 dob. The Pentax is the superior EP in my opinion. Although it has a smaller AFOV, the "usable" FOV is actually larger than the UO. What I mean is the amount of field with stars that are sharp is larger in the Pentax. The Pentax also has superior contrast. There were galactic details visible in the Pentax that were not visible in the UO. Many other visual points were first seen in the Pentax and then subsequently seen in the UO so I would say the difference was not that great, but the nod went to the Pentax. I also prefer the eyecup of the Pentax, but I don't have the eyecup for the UO so this may not be significant.
For f/6 or better, if making a choice based on performance, I would choose the Pentax. If a good deal came up for the UO on Astomart, I wouldn't hesitate to jump on it. If however you plan on using this EP in a scope faster than f/6, I would select the Pentax because of it's superior edge fidelity.
