Taylor,
I am glad you found success with the TDQ & TDK.
Here are some hints for onside kicking.
#1 Angle the top of the football forward away from the TDK.
#2 Tilt the rear of the TDK platform up.
#3 Use very little pull back on the control cord. "TOUCH"
#4 Angle the travel of the ball towards the sideline area.
Try these hints and you should start to get the right "TOUCH" and be able to place the ball consistently where you want.
Let me know!
