As, perhaps, another issue, Dave Christie, of Rendezvous Dive Adventures, 
in Barkley Sound, B.C. solved this one for me back before I began 
de-stroking.

He saw me doing exactly that, and said "O-rings too small".

He then dug out his O-ring kit, and we matched the size I had on my reg, 
and then selected the next size thicker.

He claimed that what was happening was that gas was getting trapped 
behind the O ring in the channel that it was supposed to fill, and 
putting pressure on the back of the threads, requiring at least a pair of 
channel locks to get it off.

Haven't had the problem since, until I had the reg re-built at an 
Underwater Sports shop here in Seattle, and of course, they put an O ring 
in that was too small, and I had to replace it to get the reg off the 
tanks.

Dave is one of the Greybeards of dive boats, and one of the three finest 
Captains I've dove with.
