Actually, I'd shuffle over one point of logic for a point of Charisma, since cha is the old drain stat. Logic will limit the number of foci you can have, and raising your cha from 6 to 7 later is going to cost you 35 karma while raising logic from 3 to 4 costs 20 karma. Well, you'll also need to pay to get the 4th foci that'd allow bound.
Speaking of which, binding a power focus in game costs a lot more than at creation. The bp cost is basically nothing. Might want to grab one up front. Increases your magic score across the board. spellcasting, summoning, and many metamagic things.
