I was anti-drop for a long while... until I found one that fits me, and then my attitude pretty much turned 180º-- I swear by it now. I think the issue with the "protruding elbow" is entirely proportionate to the length of the shooter's arm, as was mentioned earlier. I have 37" arms (94cm...
) and haven't had a problem wrapping tight around the tank.
So for me, it's: long arms + long drop...
