Thing is, with a stick this size, thrusts are not that efficient as you give up a lot of reach, so you cannot rely only on them.
The stick's biggest advantage is its reach and acceleration.
The strike with the highest velocity / impact is a swing that reminds of a baseball swing, where you let go of the back hand and lunge at the same time. It covers an incredible amount of distance if is seriously devastating. If you try to thrust you will come within the reach of that before you can thrust.
Generally my feeling is that these "aikido" styles with their thrusts don't exploit the sticks' potential.
