Not much point , Ned. Pyro paint grenades rarely work as expected, most fizzle out without going off. Those that work on the pressurized bladder system spray fairly well, but aren't accurate enough. The only grenade that seems to worthwhile is the Meteor storm, don't know if they are available over here yet. Cost of one grenade is about the same as 100 paintballs...you do the math.
Smoke grenades can be useful, but if there's a stiff breeze, you're out of luck. Stick to the flatline, and cover my left flank. Remind me to show you the scar on my leg
