Kevin, I was unaware that a hoop stay was available. By all means use it since it was made just for that pack.
BTW, in the 2 packs where I have used flat 1" aluminum stays I have taped them with Gorilla "super" duct tape the entire length of the stays. So far no fabric wear and I use my loaded (30 lbs.) ski pack a lot for trainings hikes. Gorilla tape also covers the internal Nylock nuts to protect contents.
I did cut off the wimpy fabric belt and insert an REI Ridgeline padded belt behind the pack's lumbar pad. Luckily it fit like it was made for it.
Now the belt is capable of supporting the max weight I've made the pack able to carry, i.e. 45 to 50 lbs. Looking at the pack it all looks "factory", not cobbled together. Yeah, it's a RealTree brown pattern camo pack but it has all my needed bells and whistles. Function, not fashion.
