I too, have no Cajuns where I live, but I either play standing up with a strap, or I rest the treble finger side on my right leg, with the bellows and left hand between my legs. I see no potential for bellows wear.

Wear and tear are normal, but there are steps you can take to curb the wear (as Hal aptly put.) It depends, really, if you mostly sit or stand. Standing -- or performing in a band -- is worse for the bellows, imho. Belt buckles as I've noticed are enemies of the bellows. I've learned to put mine on from the side of my hip. Or wear a pair of tight jeans... and sometimes I even play nekkid. In that case, the bellows become MY enemy. Most wear and tear can be "fixed" using a roll of matching bellow tape. I think Elderly Instruments sells such accessories.

I say pull it 'til it pops.
