How much energy for a Sorc?

[Sirbub]

I was wondering how much I should put in energy, thus saving them for Vitality. Right now I am runing with energy shield and am runing thru mana pots like there going out of style, but I feel that it is keeping me alive longer cause its not all going to my life. I also heard that some ppl dont like ES at all and go for one of the Ice armor skills. Ok heres the thing. Atm I have more hit points than mana so as to keep that nasty life burn curse off me and was thinking of only putting about 100 points total into energy and dumping the rest into Vit or should I put more into energy for a better mana pool. I plan on getting a Tal set and a couple Soj ring to help with the mana but is that going to be enough for me?

thx for your help
