For sneak attacks with daggers, how do you maximize damage output? Should you go use a one handed regular attack, a one handed power attack, a two handed regular attack (swing both dagger simultaneously), or a two handed power attack with the twirling about and all? If you go with the double attack, do you get twice the damage x15 (with the perk) for a total of 30x your base damage?

Come on guys someone must know

I'm pretty sure that 2h does the most damage but I could be wrong.

Sneak is the easiest thing anyway so you don't really have to maximize it.
