Pure INT s/s or Spear?

[gehtnichtgibtsnicht]

Hey guys,

i have a lvl 110 pure INT char with Ice/Lighting at lvl 110(botfarmchar^^).
Now i am wondering if i should use Spear --> more dmg
or s/s for more survivability ?
This char will only be there to log in....start bot and log off...no pvp or anything else, i will farm at lvl 106-08 mobs but with which weapon?

Thanks in advance

any comments?
