Hello Mark,
What type of telescope are you using? As a comparison, I use a collection of Naglers with the 12" dob. (22, 17, 12, 9, 7) and the 82 degree field is as wide as I need. Some observers are put off by the Ethos 100 degree FOV, as the eye can't take it in all at once.
With premium eyepieces, weight is another consideration, for example:
Naglers 9, 11 and 13 are all 180 grams, Nagler 17 - 725g, Nagler 22 - 680g.
Ethos 10 - 500g; Ethos 13 - 565g; Ethos 17 - 700g.
I am only just getting away without tube balance weights and excess weight is a definite consideration with small scopes and light tubes.
