I know the PCs in your group don't wear armor (if your DeviantArt gallery is anything to go by, I'm not sure they even wear clothes most the time)
Ooh, back in the knife drawer!
I just found the 'multiple armours' thread amusing. I knew a guy who used to try to wear multiple suits of mail in D&D. That didn't end well.
but I really don't see these two armors becoming "the norm" in all but the most Monty Haul style of games.
Hopefully not.
It's a tough line between the sourcebooks providing some new gear to get players excited, and 'Power Creep From Hell' in which the core stuff is completely invalidated by the splatbooks.
