have probably never had to do a real rescue. They really facilitate extracting an unconscious diver from their BC. I love them for that alone. My Chute II (which I use for single tank diving) has them, and I feel no need to "wire them shut" or replace them. However, my BP & wings does not have them due to the nature of the harness.
Now DIR Tech Diver... I would not want you to cut and paste everything just as much I don't want you to regurgitate everything you hear from someone and then repeat it as "fact". BUT, (the problem with the world today is big BUTs) I do expect you or anyone one else who makes a statement of fact to be able to back up that fact. If you can't than I will relegate your "fact" to being just another unfounded opinion. Deal with it.
Double125... was this the same "study" that determined that horizontal off-gassing is supposed to be the best? Unfortunately, I hear of too many studies, and never a reference to follow up on them. There are a ton of Urban legends out there about off-gassing, this and that but no real data to fall back on. If you can find the reference, I would be most appreciative.
