Oh one more thing, it needs to be balanced against your agility too. Heavy armor reduces your movement.
Find that comfortable breakpoint where you are still fast enough as well as able to take hits.
Thanks. That's good advice. To do this however I need to at least once try one of the heavier armours and compare. "I tend to think the heaviest you want to go if you want to swing well is heraldic transitional." is good advice too.
Worrying about wether you get hit more in the head or the body is apparantly too much concern. I think I will just go for one that I find very unattractive and can't afford because that's what people do. I'll also find what fits me without playing with that armour. Seems legit.
