Maurice Robinson is a member of that list and is a better (tho for me
unconvincing) defender of the Byzantine text from the ninth to 12th century
as best representing the original text. He argues primarily from a
historical view using his historical reconstructions. He does not argue
from theology like Burgon and others.
Edward is correct that this is the place to answer the questions raised. I
would advise reading several introductions to TC, esp. by Metzger, the
Alands, and some of the older ones as well. The TC group at SBL is always
an informative and challenging two sessions. See you there.
