In my experience, the sabretooth 10a handles 2x 12v drills at 14.4 volts easily.
The only time I ever blew one was when I burnt out a motor at the same time with the help of Little Hitter. So, I think that the Sabertooth will do you fine,
and have better control than the electronize. This is just my opinion, and its all down to personal preference really.
