I do the same for my backpacks and other hiking and mountaineering gear. I've bought so many high end packs, only to have the zippers fail and have had to re-sew them or hemm the seams back together. I had one mid range pack with YKK zippers about 15 years ago and its been nails on every trip I've been on. After that experience, I just look for YKK zippers now on anything I buy.
