Just a thought for the OP.
A different direction to think about. Since you are inside the house and will be plugging it in to an outlet. Why not look at a smaller studio strobe? say an AB400 or 800. lots more power at the top end, and if you are shooting lower power good recycle times. Since you did not say if you are using the ETTL features of the flash, but it might be a fun way to go.
