Hi
Jack Ingle does indeed use his BC trunk bungied and accessible at his waist. He uses an OMS wing however which has a VERY long trunk and is also equipped with a shoulder dump which he will dump from on the surface. He also does not use the wing for buoyancy. (Or thats what he said in the article in Dive Mag) A picture is available at

Go to DIR vs DIW and then DIW parade. Theres a pic of Jack Ingle from Dive Mag in there. There might be some pics of inverted tanks too.
