Marion, the Backaxe sling system is a royal pain in the ass to put on and take off. I had one for about 6 months and got so frustrated with it that I gave it away. I use a Calton Case (as anyone who has read the threads on Fying with guitars knows), and like most HSCs they have 2 D-rings on the handle side for the use of a shoulder strap. I got 2 more D-rings from the manufacturer and installed them on the other side from the handle side. I had to make small razor slits in the padding to accomodate the rivets, but they closed up perfectly with a little contact cement. Then I bought 2 heavily padded shoulder straps (about $4 US each) which clip on and off the D-rings and away I go. Clinton, I carry my guitar on my back at festivals and other gigs to leave my 2 hands free for my beer, or CDs or guitar stands. or signing autographs or whatever. Think carefully about getting the Backaxxe, though. You'd need to be Houdini to get in and out of it.
