i'd go for breton for the increased mana pool, bonuses to restoration and alchemy, 50% magic resist and a 50 point shield once a day. spells tend to level slower than weapons/armour so the higher they are at the start the better. you will have strength/encumberance issues at the start of the game, but they'll be a distant memory soon enough, while the increased mana, 50% resist magic will be with you til the end of the game
