Real grenades are a lot more insta-burst than the on-impact grenades in paintball2. That grenade is spent before it hits the ground again -- like 1/10th of a second. PB2 grens will bounce off of a couple surfaces usually before expiring. Also, real grenades seem to only cover a single horizontal range. I guess it depends on which way the grenade spins, but the two I tried, spun vertically, like a wheel, and for the most part left a single stripe of paint (not a broad splatter). Coupled with the fact that you have to toss them like 50 feet into the air or else the won't splatter, they don't seem to be very effective weapons. I think the photos look a lot cooler than the real thing. In reality, it's just: *toss* .... *thud*. "That was it?"
