I just kind of went for it. Shoulder measurement was fine, the rest will be tailored. It's really a pot luck when it comes to the various fits. I'd go to the armoury and figure out how you fit in the 184.
I have both soles so I can comment. Tomir is awesome, but at the same time it's not a full rubber sole. Dainite will be more flexible and more waterproof. The shoe on Dainite will also need no break in.
Personally I would go for Dainite since that would be an awesome wet weather show in Dainite. The Tomir is nice, but the middle will still get soaked and scuffed in a decent amount of wet.
I actually think with Carmina it is a matter of pricing. At the beginning Epaulet was the main place to get Carmina and the only place to try it on. Now there are a huge number of constant GMTOs run by people who exclusively do MTOs and provide non stop dedicated shoe service and fitting advice. It's a hard market to compete. No one else really does Aldens the same way.
