Advice from expert Monks

[Sarius]

I posted this in the melee forum but then i realised that nobody reads it, so...

I need some help deciding what to get!

I'm currently lvl 20 and my relevant equipment includes, Peacebringer, RBG, Hiero cloak, 52k, and epic. My options are:

A) RGB, Hiero Cloak, and PP for CoF and TBB

B) RBG + PP for RBB

C) T Staff

D) SoS and Addy Club

I'm looking for the most long term viable upgrade that will also help me to solo most effectively.

Thanks for your time and input!
