Not sure what F ratio you have, but I am surprised you are looking at off loading the 19 and 27 Pans.
I have 18" f4.5 and use 7, 9 13mm Naglers + 27mm Pan. Satchmo recommended an eyepiece to give a 4mm exit pupil so am looking at either 17.3 Delos or 19 Pan. For some reason I just don't like fields exceeding the 82 degrees the Naglers offer.
