Black Diamond BC Trapping Air

[Rpeiffer]

It consistantly traps air at the top of the back pad. There is an area that creates a space for the air to catch up on. When I roll left and then right it will dump. Problem is, I wouldn't mind if it got there and stayed there but sometimes it "dumps" unintentionally. Then I play the bouyancy game.

Thought of Putting large gromets in it to allow the air to pass but after looking at it I'm nt sure if that will work. Anyone else have this problem and find a fix?

If I understand you correctly I'll get that from time to time, I'll usually just roll to either side and it's gone, The thing that confuses me is your statement about "dumps" unintentionally, do you mean it vents thru the over-pressure valve?

By "dump" I mean the trapped air escapes and changes my bouyancy. So I'm forced to either add air to my BC or position my self to replace the air that was trapped.

If I don't change my diving "posture" in the water nothing changes and there is no issue. But if I go vertical or roll/turn then the air escapes/dumps and I have to make an adjustment. A bit of a PITA.
