Paintball brand for multiple paint guns?

ok first off the best paint to buy for each of them is premium but it costs 60-70 bucks for 2000 if you dont care and are willing to spend the money on that paint reccomned buying that and for four of you 4000 paint will probably not last you unless you guys are extremely conservative of your paint for me four people would go through that it 10 minutes because I dont woodsball I speedball for a couple of days you would probably need 6000 because of your guns and that your woodsballing
