well, its really your call, but the Kite shield stats (especially player crafted) are STR/STA/INT, where as the Tower Shield is STR/STA/AGI. since the SK is a fighter/mage hybrid, their spells' damage is based off of their intelligence, so a higher intelligence, the more damage their spells will do. The Tower Shield (can't remember is SKs can even equip them or not) is better designed for Guardians or Berserkers who are not going down their Stamina tree for AAs.
