I have a 12" newt & use ES eyepieces (6). At 82 degrees they are really good for my eyes. A 9mm 100 degree is good too. My most used are 18mm 2" & 11mm 1.5". See if you can look through some before you buy.
Having left my lens case at home, I was generously lent a 13mm ethos which I used for an entire star party week, fabulous views. From that experience I found I don't need to buy Ethos to be happy with my viewing. I could halve my eyepiece collection & have all tv but for now I'm happy. Hope you get to the same place with your decision.
