My birthday present to myself this year was a Mono double gig bag. http://www.monocase.com/mono-dual-bass.asp I do regular gigs with a funk band where I play 5 string fretless and 4 string fretted, and schelpping 2 gigbags was getting to be a minor drag. I had a Mono single and it was by far my favorite bag - protective, easy to carry, well built - so I sprung for the double. I am really happy with this bag. It's been to a couple of rehearsals and gigs now, and it's solid, carries just enough stuff, protects my basses really well, and makes the cartage that much easier. Great bag. Pricey, but well worthwhile.
