I use Schaller everything, wherever possible. There, I said it.
Twenty years ago the band I was in was invited to tour the UK on a self-financed (I.e. cheap) 42 date tour of England, Scotland and Ireland.
Lugging the Anvil flight case with my long-scale series1 in it (it fit in the back of a London cab with four people, no prob) was turning my right hand into something out of a Vincent Price movie.
Reasoning that I needed to sling that sucker over my shoulder or get used to playing bass by using my right hand as a club (the Lemmy technique), I took the Schaller straplocks off my guitar and went into an unbelievably filthy junk shop in Glasgow:
.. And with the help of a surly, incomprehensible proprietor, I drilled a couple of holes in the road case and bolted strap buttons on over 2-inch washers (apparently left over from the Crimean War) inside and out, to distribute the weight.
I attached the straplocks on a seatbelt hacked from a car out back (with more washers, of course) paid him what I assume was an exorbitant amount of their money, judging from the fact that it was the only time I saw him smile, and effected my egress.
It worked a treat, as they say (I think). I finished the tour with a pronounced 45-degree starboard list to my spine from lugging that monstrosity around on my shoulder, but at least my right hand didn't become some kind of crab claw thing on the end of my arm.
They're still there. The seatbelt is hanging on my studio wall, handy for self defense if nothing else (I ain't picking that damn road case up again, ever) but I know if I had to, those Schallers would hold up just dandy.
