pvp blizz'r belt question

[Nex]

ok my blizz sorc atm is wear snowclash thats gives me 3 to bliz and 2 to 2 to glacial spike im pretty sure. but i was wondering if arachnids would be better to use. i realize i mite loose a bit of dmg over it but i has nice fcr and slows target, which is kind of needed with a blizz sorc. atm im pumping 14-15k dmg.
so i was thinking i could vary it a bit by switching my coh for a p bliz ormus with 5/5 cold facet in it to beef the damage back up.
so frater i thought you mite be able to help me out a bit in this field, or anyone else who has gg knowledge of pvping.
also if thise helps this is my gear:
Perfect Nws with 5/5 cold facet in it
23% maras
ds coh
Perfect spirit
Perfect Death's Fathom (im pretty sure its duped but ive been temp perming it just in case)
Mage Fists
Snow Clash (i have 2 spiders in stash)
Soj & BK
9x cold gcs
anni
torch
fhr sc's
on switch
6 bo cta and sprit.

can you help me out a little?

ty,
nex.

I have a load of work to do at the moment, so please bump this thread and I will respond in the evening.
In short:
Arach > Snowclash (Snowclash is only good for BM absorbing)
COH > Ormus

[Nex]

heres the bump. so are you saying arachnids is better?

[FraterPerdurabo]

Basically, it's what I listed above:
Arachnid's is better than Snowclash and CoH is better than Ormus, however individually they mean nothing. You just need to hit 105%FCR breakpoint with all your gear.

With your current gear, you only have 75%FCR, which is ridiculous:
35% Spirit
20% DF
20% Magefists

So you should add:
20% Arach
and substitute SoJ for FCR ring.

Alternatively, you could substitute the BK, but since mana is quite pointless for a Blizz sorc, I would stay with te BK for more life. Unless you are ES. If ES, you need a different setup, so let me know.

no im a full vita build, no ES. does fcr make the time period between casting go blizz faster so u can cast it more than usual between that time period?
