I picked up one of the rubber grenades from JT. Ricky, I see what you mean about the usefulness of grenades, and I mostly agree with you. But twice now, in games that I've seen/used grenades, they do seem to have a use. At just the last game at SI, I used one to flush a guy out from cover when he was pinning us down. Didn't kill him, but it freed up and gave opportunities to 3 or 4 of us. And for $10, it's not a huge $ sink.
Thanks for the advice, but I think the problem actually is the phone line we have connected to the modem is crap. We have a 56k modem, it usually only connects at about 20-30K.
