Water retention

[Big voh]

I'm starting my bulking cycle in a few weeks time, and i'm really concerned about water retention. Where i'm from arimidex is not available. My question is can arimidex be substituted with provilon?? or should i stick to nolva!! or is there any other compond i can use to combact the water?
my cycle layout:-

1-4 Dbol (injectable) 50mg/ED
1-12 Equipose 600mg/EW
1-14 Test E.750mg/EW

PCT Nolva, Clomid, proviron & HCG

I don't know about the substitution but I'm on a oral Dbol and test E now with Ldex and nolva with no noticable bloating that I can tell.
