The Naglers and Ethos are obviously desirable in your scope for their wide apparent field of view, but only some of them have long eye relief. How do you feel about the eye relief/comfort of your current eyepieces? If you like long eye relief your choices might lean towards the type 4 Naglers and Pentax XW's. If you find shorter eye relief ok (10 to 12mm) there are a lot more Nagler eyepieces to choose from.
