I'm not putting a £2k+ guitar in a gig-bag or even a 'semi-rigid' case, Silas. But it's a personal choice thang, and I guess it's a good solution for anyone who's prepared to sacrifice security for lightness. If I was taking a £250 'beater' out, it would do just fine.

BTW, this isn't meant as a slap-down to anyone, just my own POV based on the instruments I have, and which I want to take the best care of.
