So.. did a bit of searching here and there and I do believe I see people saying that their stuff is durable, but I've seen some people suggesting not using it for check-in. I plan to check-in when necessary, but I may only need to fly about 4 times a year. Is GT a bad idea? I was looking at Tumi and Hartmann as well but I really like the appearance of GT.. I'd also like to have it for 10-15 years.
