All this elongated last talk recently so I decided to wear the longest ones I have. Alfred Sargent (106) which are about as long as my C&J (348).
Back to G&G, I think I am going to go with 6.5/7E on the TG73 last. I went to the mansion and tried the 6.5/7D Numan (TG73) and it was just a tad snug so hopefully an E will suffice. Could probably do an F but that might take to long for MTO.
