Yeah, he's right, never
on your shoulder.
Put it just in the crook of your arpmpit. Pull it into you so it doesn't flop about when you run.
Keep your elbow tight towards your body when you aren't running and want to keep a tight line against a barricade when you're snapping.
When you dive remember to take the gun away from your body, or you risk a broken collarbone
.
This is it. (sorry, stole another pic out of someone's photobucket)

If you're finding it uncomfortable to hold your marker, your setup length might be wrong.
If you hold the marker in your hand (palm up), with the bottle on, the bottle should be only slightly longer than the crook of your elbow. Definitely no shorter. No dropforwards!
Everyone and their dog used to use one, but it really helps snapping and stability when you're running, to have a bottle against your body.
And if you're still finding it uncomfortable, just keep your setup around, and hold it while you're watching telly, you will become comfortable with it, until it becomes merely an extension of you, and you forget it is there at all, in games.
He's right you know
, he couldn't've been that bad.
