StSomewhere:
It was a joke. Get over it. I didn't even direct it at anyone. You asked for the rules and I simply stated what the original two DIR (f/k/a hogarthian) rules were. The term stroke is a reference to divers that have been shown a better way of diving and stubbornly refuse to do it. It isn't some sort of a racial slur. I also actually gave you an answer.
Read my first responses, it covers why a trilam. I later addressed some of the reasons why the TLS is preferred. Some, particularly the "newer" converts, either have an agenda for pushing other suits or want to justify the suit they bought. I gave one answer and explained it was a single example but did not want to continue to argue about it. Here is another, the zeig heil valve placement is absolutely stupid. The same people promoting that are promoting the other suits. Draw your own conculssions.
A DC suit works fine for a typical cold water 20-30 minute mix dive. In general, properly experienced DIR divers recommending these suits are giving you the correct advice too. There is a problem in the thinking that the newly minted DIRF student who has just been exposed to "current" GUE philosphy has it all sorted out and is in a better position to explain DIR. But, you are free to seek advice from whomever you want.
And no, discussing the minute details of why a suit which is very slightly better makes a huge difference when you are looking at 3+ hours on the trigger, carrying multiple stages and scooters, etc. cannot be properly conveyed on a list. Plus the people at that level don't need a list. Everyone likes to pretend their diving is different. It isn't. The only difference is when those of us that primarly cave dive go open water diving in cold water we add a lift bag and get to carry less gear.
