He asked who makes good luggage...I answered...Yeah that depends on a lot of factors.
I agree its heavier but not by much. The little bit of extra weight is well worth it for me.
The bag I posted earlier has a hard bottom and it lasted over 10 years (year round) of heavy abuse in extreme climates and conditions until I drove over it with a sand dumper.
It also comes at under a third of the price of a Briggs and Riley bag in the same category and unlike you Ive never lost a wheel and had to get my bag fixed at an airport.
For someone like OP who rarely travels and will use it maybe a handful of times I think its a bit rediculous to buy something that expensive when theres way cheaper options, that are just as good but maybe a little bit heavier.
Just my 0.2 though.
Whether it's right for his application or not, I can't really say.
