Exactly right. A typical "fresh" paintball will bounce if dropped onto concrete from waist level but break if dropped from shoulder height.

My Sporran will probably look very plain...pretty much like a muzzleloader's possibles bag. The trick is to orientate it so that it's not "bouncing" as I run so I don't get "tapped-out" by it's weight (of things in it). Perhaps a wide band of Velcro securing it to the front apron of my Kilt...not sure yet, I haven't even started on one yet.
