PRACTICE makes you (your plane) fly smoother. If you don't have enough throw you may not be able to control the plane or recover from unusual attitudes or prevent a crash if something goes wrong. If you have too much throw you COULD cause accidental stalls, secondary stalls, spins and snaprolls without intending to. ALWAYS set the plane up initially according to manufacturers instructions until you are familiar with it. THEN you can experiment slowly if you wish.
