SS Divers + FC Divers...Yes or No?

[le-temps]

Gentlemen, this is my first post on this Forums. I'm a bit confuse and need some advice to decide my next move.

Here it goes : I already have SS Divers and I have been eyeing FC Divers for sometimes. Since I read on this forums that FC Divers will be discontinued, so I'm kind of worry if I don't buy it now, I won't be able to find the new FC Divers to buy in the future. I'm not gonna sell my SS Divers, so the question is :
1. should or shouldn't i buy the FC Divers since my AD is having it reserve for me?
2. having two AP Divers, same movement but different materials...stupid or ridiculous?

Look forward for some comments....
