Addition to my previous... you asked what use they all are in P6... well the P4 and PPP ones aren't of any use... in the same way that the P6 ones that appear for say P4 users will be no use to them.

Vendors often supply the 3 versions of the same MAT with their product... rather than have 3 different products on sale... one for each version.
