If upgrading from the 8" you will want eyepieces that handle a faster scope. As you have mentioned the likes of the televues.
What are your target objects?
For my future use, and I pretty much am interested in everything from planets to DSO's, in a 10" or 12" dob I've shortlisted pentax xw10 and denkmeier 14mm based on the excellent feedback here for dso and cluster use. I require good eye relief as I use eyeglasses and these both provide that.
