I've got a Dock Nickle's SC rig. IIRC my rig was used to design the WTF Stalker SC rig.
I like how it fits. I also stuck a pouch on the front of mine for easy 10rd tube dumping. I never run more than say 6 tubes even though it has space for 14, and I never carry 12ies in it, I just put them in my pocket.
Found a pic of mine on my Photobucket. I was wearing my painting shirt lol.
