One more consideration. Sometimes falling is a b*tch. I've noticed sometimes there are small places where it looks like you are falling five feet, but you take a lot of damage. Also sometimes the griffin drops you midair etc. I've heard that carrying a large ammount of weight can double this falling damage. Maybe I'm just a clutz, but especially when running away from things, I've found this damgage to be quite significant and I'm not sure if I'm willing to increase it. Btw, I'm currently using 6 14-slot 10%wr bags. Any experiences from box users?
