I cant think of any reason to limit your drive motors to 30 amps when you are allowed to use 40.

Almost right, motors start at stall current with full voltage applied, If you are ramping Motor speed up, useing a Victor, voltage will be less than full. And Current will be less. This would not apply to motors which are switched on and off with a spike. Hope this helps.
