Uncle Bagger,
I am saying this because... Level if not explained properly , some people will do un-cocked. (Wrist and thumb -level )..... then there is no way but to struggle , start hitting high slices or something. Sorry Grape and Uncle Bagger, that it didn't come out well.
Just in case. level is trying to extend the first knuckle ( belonging to forefinger) as far away from the wrist joint( thumb side). thus forming a Wedge between the thumb and wrist ..
And if the right wrist is level in the first place and the arms are hanging nicely below the shoulder at setup. (some people have their arms in front of the shoulder and also makes the job slightly tougher). there is less reason to struggle to fight the right wrist from cocking... Its then the job of the right elbow /forearms job to cock the left wrist and load the PP... Thus it becomes easier... ( not brainless , ok ba.. brainless of me to use that word

)
cheers
