Madcow 5x5 is a good routine but on gear you would be extremely limited by its slow progression.
I like that stile of training too.
Look into jim wendlers 531. Its ramped to a heavy set like madcows except the final set is as many reps as possible. That way you can continue to make rep records every workout.
Theres a lot of different assistance templates to choose from to suit your goals. Im doing the boring but big template. Its fucking brutal
