Holding your gun...
Right-
First things first. Learn to hold your gun as many different ways as you can. That means left handed, right handed, lying down, cross-handed (a la russian legion), with your toes (I can do it, ask of the Abbots to show you, it's so easy), and with your elbows in the event of sudden amputation of your hands, because, hey, you never know.
Judging by the fact that you've got "team spod" plastered all over your damn sig, and you're not seen without your girlfriend (that'd be Eric), this has gotta be Sam. Sam, you've got an Angel. Just stay tight and get your damn hopper in. At training, both you and Eric had your loaders out about, oh, 6 miles from your barricades. They're big targets-tilt your damn gun and get them in. Other than that, whatever's comfortable, I suppose. Though I would listen to piper. I've seen him eat like, 6 pies, and then come out at the Wurzelbash and kick my ass. Keep in mind, I was shooting a doorstop then (er, shocker).
Peace, hope this helps.
