Just thought I would leave an update, since I have been using my scope a bit lately.
A little while back I found an amazing deal on a Pentax XW 14mm (I gave a lowball offer to someone on ebay who took it). However, as I suspected, I don't seem to want less magnification. The view is comfortable, sharp and everything you would expect, but I don't like to give up the extra magnification of the 9mm.
The 9mm Nagler is amazingly sharp, limited only by atmospheric haze. The views are so wide that is is almost hard to see the whole thing - there is no circle - just view everywhere. It is also very small and light compared to the Pentax, making it balance perfectly. The one flaw it has is that the edges of the field are curved (as primarily an astronomical eyepiece, I believe this is purposeful to ensure pinpoints for stars to the edge). This is very distracting when panning, and can even be somewhat sickening at times when searching around for an extended time.
So, I will probably end up with the Pentax 10mm XW, which is probably the best eyepiece for me.
