With todays current emphasis on lighter equipment have the demands of modern paintball now dictated that it is now always preferable to use polystyrene cups versus the heavier but improved ergonomics of a mug or would you say the difference is negligable?
you could always get a plastic mug to save on damage during transit and would make for a light, tight profile for behind bunker sipping. im sure they would be available in many excellent colours and with it being a glossy plastic you could put all yer favorite stickers on the sides. agg heaven
seen a tin mug with a working caribena as a handle, just clip onto your kit bag after use (also the caribenas come in different annodised colours, surely a paintballers ideal Beverage Action Device (BAD patent pending(fu sp)))
