the hardbag for the GS Mini is quite a bit more 'substantial' than the
gig bag that comes with the baby, big baby & 100 series models, imho -
the 'lid' does have a liner in it, although it is not quite as heavy or stiff
as the 200 series hardbag, other than that, they are very comparable
i might trust an archtop plywood hard shell case that had interlor padding &
lining that was an inch thick around the entire body of the guitar a bit more,
but compared to a thermoplastic case with aluminum frame, i'd take the hardbag
ymmv
