Good advice.
My parents and I did SCA when I was a kid, and I recall a couple LARP events. But SCA combat was a bit more brutal. You had to get certified to use a weapon, which was a rattan club of the right length covered in duct tape. Your armor had to be inspected and certified as effective enough to be ok when beaten by someone's club.
Mom and Dad wore a quilt gambeson, under 1/2" boiled leather cuirass, under mail shirt. Steel helmet with grille visor. Limbs covered by the same leather with metal joints and flanges. Articulated metal gauntlets. Big heavy boots.
Other people wore some crazy stuff. One guy wore some really nice plate armor. Another made scale armor using thin leather with 1/2" pickle-barrel plastic plates riveted to it - multiple layers of it. Dude would seriously not notice when someone hit him.
And then there were people classified as "lights" who wore little to no armor and used bows or thrown weapons. A "heavy" didn't strike a "light", he just had to walk up and point with his weapon, and shout "light, you're dead!" and the "light" was supposed to shrug and wander off for a drink.
Even a "heavy" could have a throwing weapon though. Usually a javelin made from PVC pipe, or an axe made from a "9" shape of garden hose wrapped in duct tape so the circle was covered across.
Any decent hit was supposed to count, and if you got hit in a leg you'd go down to your knees, if hit on an arm you had to not use it. But some people ignored hits, which was frowned upon and called "rhino-hiding".
You could get hurt despite the armor. One time a guy really whacked my mom and she had this huge bruise across her shoulder / upper arm across a bit of her back. Coulda broken something.
Also I recall a story about a guy who, during a war event where two lines charged each other, his martial arts training kicked in automatically and he front-kicked a guy instead of hitting with his "sword". That's not allowed, I guess mainly because otherwise it would turn into Thine Platemail MMA.
Generally mobility was good, standing up wasn't really a problem, but you would get REALLY hot and dehydrated after a few minute's heavy fighting / running in a Washington summer. And you couldn't do it when it rained because the mud would make it an impossible slog.

Sorry if that's off-topic, nowhere else to put it.

Related to LARP, have you seen Unicorn City and Role Models? Hilarious stuff.
