I don't think any real wreck diver (or cave diver for that matter) will argue that you need to be in perfect horizontal trim and have your left pinkie up your ******* to booth. Nope in trim just means in a position to avoid dropping visibility by silting up ****, avoid getting holes in your drysuit or damaging gear on any sharp ends and edges, etc. I think you would agree to this...
All those positions, all the different kicking techniques, they are just tools in my toolbox... and I take out whatever tool that suits the moment (and even then it depends on what kind of gear I'm using)... I might switch 10 times during a dive to a different kick, and I can be upside down or sideways if I'm trying to snake myself to the engine room. Is horizontal one of those tools... of course, and with my normal gear setup I can do hours of deco, almost falling asleep.
To be honest I don't get this back and forward arguiing at nausea about a very mood point... who cares?? The only reason I'm reacting in this topic is because inevitably someone is dragging DIR or GUE or UTD in the discussion, calling us TRIM NAZI's or whatever... yes during a course there is focus on horizontal trim, specifically on the entry course (fundamentals), because many people don't have the "horizontal trim" tool in their toolbox yet, just like it is (and should be) in every entry level technical course... but that's it...
