I know that even 100 arcminutes isn't enough to get all of (the) Pleiades, but it's a compromise; I don't want to go any wider. I have no problem finding and seeing them in the 30mm. Heck, it's a naked eye.
Sorry if I seemed contrarian to some of you folks. I appreciate your opinions, especially those that explain the *why* of your experiences and opinions, given the huge number of variables at play.

Thanks.
I think you're being very reasonable, thinking, asking questions. I would not base this decision on the Pleiades, to see the Pleiades, to properly frame them takes maybe 2.5 degrees.
But the virtues of a 30 -35 mm eyepiece in an F/5 scope are wider fields and brighter images. Brighter images are particularly useful with narrow band and notch filters.
