Well I remember the first one that you beat me out of.......
Anyway I don't know about a specific name for the different types of Moro shields, but in general they are called
taming .
By the way, even though the first one is lighter, the Igorots in the north also use lighter wood like this for some of their shields as well, including some of the combat ones.
Also if I am not mistaken, some of these had a place in the middle to place a metal spike, although I have yet to see such an example.
