I was wondering, I haven't paintballed yet but I have held a marker before, if anyone had any tips on walking the trigger... without a marker. I was thinking for when I get bored or am in school I can make use of my time. Thanks.
You could put your pen in between two fingers in your left hand and have it slightly away from your desk and walk it with your right hand. Tie a rubber band around your two walking fingers and practice like that. Walking a computer mouse is a good way aswell. The best way would still be to practice on your own marker.
