I choose armor depending on which class I am playing and which would benefit most. Glittering Jacket is way to heavy. I play magic users and hunter/sniper. So I like my armors to be rather light. My wizard uses a mink coat, but that's because a lot of his other gear doesn't weigh hardly anything.
I like to be able to pick up stuff. I see people who become overweight with just all their main gear+regularly carried items...like meat/cake/whites, grape juice, ygg leaves...or whatever else they need to be carrying...especially other armors/weapons to switch to when needed...it all makes you super heavy.
