I really don't see the point of these hybrid semi-rigid cases. The Protec is so heavy and cumbersome I might as well be carrying a hard case. There's no chance I'd get on a plane with it and I doubt it would protect my bass from baggage vandalers whereas I've always sailed onto flights with a soft case.
I'm beginning to think that the people who design gig bags are trying to make them look as fancy and "stylish" as possible to try and justify charging more money and to make them stand out from the competition. A bit like rucksacks manufacturers. I just want a simply designed, durable, lightweight soft case with good sized, practical pockets, no naff logos emblazoned all over it or fancy stitching or luminous pink piping FFS!
