Boffer Larps rule!
Tho, I understand in England and Europe, they use Latex foam weapons that look really sweet, but are much less soft than our US pvc pipe+foam versions. They're also much better at pulling their blows, I understand.
I haven't had the best of experience with the NERO games I've played, or their immediate derivatives, tho I have heard very good things about the original Wildlands and the newer Wildlands South (never got to play them *sniff*). In fact I have a friend who I think NPC's Wildlands South, and if you like that sort of thing (and I do), it's supposed to be very good. I generally prefer the smaller LARPS that host maybe up to 50 people, I feel the extra personal attention that one gets tends to be significant. And it seems to me that boffer LARP quality tends to degrade the further you get from the Eastern Seaboard. Here in the Northwest there is Legacies (
http://whatsyourlegacy.com -hmm seems to be down right now), and it seems popular, but it's not my cup of tea.
Remember, no one swings at full strength or they're outta there, post haste. Tho it sometimes takes those SCA people a little while to settle down

Granted, in high-stress, high-adrenaline situations, the hits tend to be harder, but the adrenaline also makes it easier to shrug off. Also, wear armor. It doesn't have to be SCA quality, and it will degrade the blow's force a lot.
And while it is true that to some degree you need to have a minimum of physical skills to engage in the combat aspect, you'll usually need to throw small bird-seed packets for magic (tho there are point-and-shoot varieties), even a pretty un-coordinated doofus like me can do pretty well in one-on-one combat. Sword and shield is your friend.
Also, in my experience LARPers seem to be *more* willing to risk a character's life than their tabletop counterparts. When you get 2 or 3 free resurrections, why not jump into the middle of a firefight? Tho after running at high speeds downhill thru the woods on a dark night one time, sometimes the adrenaline takes over a bit too much.
I've never seen a serious injury at a LARP, never even heard of one. The worst case I saw was due to a guy using a questionable weapon (if your LARP isn't serious about regular weapon safety checks, find a new LARP) using too much force and he knocked a friend off his feet.
Finally, as to antagonism between LARPers and tabletop gamers, I've never met a person who only played LARP. There are some things that can be difficult to do inside a LARP, and a good tabletop game is far less time and money intensive then a good Live Action Role Play weekend.
