I recommend staying away from Arcane Explosion as it is quite a threat producer.
Actually, this isn't entirely accurate. Complex, but not accurate. You see, with 2 points in Arcane, AE becomes the lowest threat AoE in the mage's ************ behind Holy Nova in being the best damage for threat AoE in the game). What makes it perilous to use is the fact that you do all the damage quickly and at close range.
At close range, it only takes 10% more threat than the tank to pull aggro from him, instead of the 30% extra you need at ranged. Couple that with the fact that so much damage is done immediately instead of over a period of time, and you have a problem. Especially when you consider that the paladin tanking does his threat in many small increments(Ret Aura reflects, holy shields, consecration ticks, etc).
It also has the drawback of being very mana inefficient.
I'd recommend rotating Flame Strikes with Blizzards, myself, with a spec like you suggested, but mostly because the damage is done just like a paladin's threat, in multiple smaller increments such that over time it adds up to a lot.
