Joel,
I am vastly unfit and will not entertain the notion of a paintball day. On the weekend I bought 145 vinyl records for R0.50 each - yes, yes I over paid for them but they melt a treat in my oven and make really cool oddment holders if you place them on top of a pot first.
I was also thinking of making handbags from them but I see someone else has already done that. Throwing them like frisbees into a concrete wall to see how many bits you can smash off with a single throw is also worth 50 cents a pop. Fun and cheap entertainment for the whole family.
But perhaps making body armour for paint ball from them is not a bad idea. So if you need a few, let me know. I will have them pre sliced and diced, good to go!
