As far as the bags go, think of one of the plastic produce bags that are on the rolls and that you put your fruit in at the grocery store.
Here is a bit of advice, we found this out the hard way.
When pressing the shirt down the barrel during loading, you might feel a large static field/charge building up. If you can feel it, it's already beyond the point that it could cause damage to static sensitive devices such as the FET's in you Victors. So to reduce or dissipate this charge, add a grounding strap , cable or chain to the bot to ground it. We added a short length of chain to the bottom of the frame. It drags on the ground and makes a huge difference.
