Ok, well, I very much like this guide, however, I want to ask a few things, firstly, why stormshield?
You have said because of the DR, however, compared to HoZ, you not only lose the res, but the str + dex (or w/e the 2nd mod is) is also a big loss. Now, yes, the DR difference is great, however would it not be better, to do;
Shield ~> HoZ (Ber'd For DR) Gives Res + Str +++
Helm ~> CoA (Can Be Same Res As Ral'd Shako Cept ALL Res) Double Ber'D for the missing DR
Now, yes, you would need more STR for the CoA, however with the boost from HoZ, it should help

You do lose a few DR, however you gain a great deal of Res and Skills and obviously, def with Holy Shield and what not.
Secondly, the belt. Personally, I don't like using Arach on HcL, I feel much safer with TGoDs. From this, you gain Str and what not, however lose some FCR.
So, instead, how about;
Rings ~> Raven (Or Dwarf) + 10 Fcr / Str / Mana / Whatever You Want Ring
Belt ~> TGoDs
Ammy ~> +2 / 5 FCR / Str / Res / Whatever You Want Ammy
This gives breakpoint, more Str (incase you need it) and it feels a bit safer IMO?
Lastly, Merc. Now, I like the idea of having broad sword and what not, however, what I don't get, is why you use Tals helm?. I know it gives life and what not, but what about Gaze? Its 2 less life leech, with extra DR. And of course, you can socket it with a P Ruby, or if you really need the leech, amn rune (I think it gives leach in the helm?)
Anyway, thats my oppinions, perhaps you can tell me why / why not my plan would not work?
