In the "For What It's Worth" Department, I had a 'Tech Tuesday' and restrung my Cargo. It had Elixir Nanoweb 11's (extra-lights). I put D'Addarrio EJ-17's on it (13-56 medium PB for the uninitiated) and checked the relief and action over 2 days.
Remember, It has NO truss rod.
Absolutely NO change.And the action is delightful. I enjoy the warmer less sizzly sound and greater tension, too.
