What brand/type of Shooting bags for PRS ?

I'm personally a fan of the Tactical Udder from Bison Tactical, just because it's got more side-to-side rolling stability than a Wiebad Fortune Cookie or a Armageddon Gear Gamechanger. That said, the disadvantage of the Udder compared to those bags is that it's bigger. Between those 3 it really comes down to personal preference more than anything else.
 
I have a shit ton of bags, all different companies.

Get Lite OG Game Changer - mammoth type field matches and combat. Makes a good pillow weighs 2lbs-ish.
Smedium - PRS bench rest barricade square range situations.

I also like lite fill warhorse clede.
