I bought a Lojel Juma 4 (double) wheel hard case last year & it's done 6 short internationals- Excellent build & quality.
My 2 other checked luggage for last 10 years (300+350 flights) are
Samsonite clamshell 4 wheel hard case (U always see tons of them @ bagage claim with Japanese owners)- truly bulletproof & heavy. Only replaced wheels.
A well made generic 2 wheel roller type soft case. Strong single zip only, excellent handle, extra buffer materials on wear points, tough nylon & most important quality wheels & mechanism. Only re-sewed zipper.

My advice. Treat the bag like a handler would in the at store. Dont be afraid cause it's going to save U heaps of frustration later in warranty emails, photos, receipts etc.
