I found over time around 110x was my most used in both a 10" and 12" dob and as such leant towards spending the most there.
Nothing wrong with TV plossls ,they do have a narrow fov and tight eye relief in the shorter f/ls
I have an es 8.8 and really think its a decent eyepiece , not quite as nice optically as the pentax 8.5 I replaced, but the wide field sort of trumps that for me ,so no regrets.
Its all about what matters to each of us
I like the ultra wide fields and bought one in my favourite focal length but couldn't buy another in that price bracket.
Low power I find 68* is enough for a finder type eyepiece and am happy enough to keep it that way,theres lots of not to costly options in whatever you decide
so best of luck
