Portabag is the sturdiest (non-hardshell) case…that I’ve found. Agree, it’s a bit heavy, but you know a bass is safe inside!
Also like the Gator Pro Go series a lot!
My 30” scale MTD came in a TKL electric guitar gigbag (and Roscoe basses also ship in the full size version…) It’s a fairly decent padded bag, lightweight (and not floppy)…not a lot of storage, but it’s also the thinnest bag if you have minimal storage space. I like them better than my old Contego’s…maybe C’s have been improved???
TKL Vectra® IPX™ Electric Bass Impact-X™ Case
Finally, I’ve never liked Mono’s…tried all the versions—they seemed to be quite popular, but they just didn’t do it for me.
That TKL looks like a nice bag. Did some searching and see that they make a double bag in that same format, too. Looks like it's the style that has one compartment with a divider rather than two separate compartments, which is not my choice, but not a deal breaker I don't suppose. American Musical has the double bag on sale right now for $179.95 (from $269.99). I tempted to try one since I know it's just a matter of time before my Mono is done.
But, knowing the quality of the Access bags, I'm tempted to try their double bag, which does have a compartment for each bass and appears to have more storage space. Decisions, decisions...
