I'm looking at getting a decent new gig bag. It's between the F1 & the Protec Contego (the protection racket looks interesting and is cheaper but it's bulkier than the other 2 right?). I would like to be able to fit my markbass lm tube inside the gig bag. I've been told I could do that with the Contego, what about the F1? The F1 is a bit lighter but bigger. Which case is bulkier?
