My buddy is under the impression that it's possible to set up your rig (by rig I mean the whole kit of dive gear including BC, weight belt, everything) so that your trim is completely neutral. What I mean by neutral trim is that there is no particular orientation that is predominate; in other words, whatever position you get into, it takes no effort to maintain that position - you don't have to resist flipping over.
....
Here's what I'd like to know from you guys:
1. Do you have neutral trim? If so, do you dive in cold water?
2. Do you wear weights that are located at the bottom when you are in your normal diving position?
3. How much effort does it take you to return to face-down, horizontal trim if you have gotten onto your back?
4. How much room to maneuver do you need to get back to face-down position? (I ask this because I only ever get discombobulated when I'm in a tight space, and have to try not to knock into everything getting back to trim)
