How are you going to wire it so you don't blow a fuse when you accidently press both buttons at the same time? There are ways to do it with the right type of pushbutton switches, but I'm not sure you can find small enough switches with the right features.
I think the toggle is easy to use, but they are slightly more prone to breaking if you crash and hit something just wrong.
