Rank 9 bonus

Hello guys,
i'm wondering if go for a full rank 9 gears,
but this mean i have to drop my previous idea to go for -channel set gears,
getting different pieces of armor (the once with -channn bonus).

My question is simple
does anyone have a full rank 9 wizzy set (all pieces)?

If yes,
what kind of bonus do you get from it?
I mean...
with TT99 gold you get 3 different bonus
having 2, 4 or 6 pieces.

Is rank 9 the same?
Can someone explain me which are bonuses (step by step) if they exsist? b:thanks

ty in advance to all the kind ppl who will spend some to answer me.

bye
