Got my suit in the mail, overall mixed success.
My number one conclusion is
be very careful with the "Allowance for extra thick undersuits" option. I regret selecting it as it made the upper body and arms huge. Attached picture is with me wearing a 400g Thinsulate undersuit. It may be a more useful option if you're a really big person, but I have a slight build despite being tall.

Otherwise the suit was made exactly to specs. Trilam seems cheaper/thinner than my Santi. The pockets are nice and roomy but the inner pocket has no way to drain and cheaper/thinner bungees than my Santi. The zipper placement is a bit odd, it does not go nearly as far to my right hip as the Santi does, but seems useable and does not hinder donning the suit.
It will be a few months before I dive it, I'm sure it'll work but I'm a bit disappointed in making the sizing mistake, oh well, live and learn.
