I have the 31T5 and love it to bits. In an F/5 scope you could certainly get away with it, at F/4 it is probably not a good idea. So if ever I get a really big, fast Dob I will have to (:)) get that 26T5 to fill the "gap" between the 31T5 and the 22T4.

Different scopes require different EPs, ergo more scopes means more EPs :icon_salut:

Helpful, ain't it?:):evil6:
