Lou, my flexibility is leaving early in the morning on Friday the 19th of December and getting to Vail area early in the day on Saturday, if kids can skip school - will be in Vail in around noon. As there will be no skiing on Saturday for me, I may as well visit Greg. If kids have to be in school on Friday, then I will not make it to Vail until late in the evening on Saturday and I will have to pick another day for boot fitting. I will not know that untill close to my vacation time, so do not want to be scheduling anything so far in advance.
I understand the reason of plugs being what they are. In my understanding "they are built to transfer energy to the ski in the most powerful dynamic way" is the result, on major part, of very close fit to the skiers foot and leg. My "refering to plugs like they are square blocks of plastic that get custom ground to your feet" is exactly what I thought, and this is the reason for my posting these questions here. My current boots had to be adjusted in terms of cuff angle, flex, etc., they also had to be punched. On the other hand my heels are so narrow that none of the non-plugs worked for me - they were just huge and gave me no support at all, but no work had to be done to the rear part of the plugs.
