Ok guys my apologies for letting the thread denigrate to personal insults and body parts , Downbylaw is quite right and to him I personally and openly apologise. He is after all a fellow left handed and should, like all lefties be respected, we do after all sit to the right hand side of god.
My theory and it's only my theory , on distance is that left handlers are simply right hand tennis players playing a powerful backhand shot, feet planted hips rotating and shoulder unfurling and realeasing the wound up power. To build speed you drag the club towards the ball with your right hand and at the same time rotate your hips, the left hand is doing nothing but gently guilding the clubs direction , club, racquet, bat it's doesn't matter, the power comes from the hips and the right arm and shoulder.
BUT accuracy is not guaranteed, that comes with skill and experience , a 5 deg error is not to bad at 200y but at 300 it's is exponentially bad and probably out of bounds.
