I think people misinterpret the kick back leg. Maybe say widen your stance instead.
Don't construe that with putting your weight on the back foot, the weight is still forward as you said it should be.
Above mentioned about helping with the bend angle of the back, your exactly correct. By widening your stance, your lessen the angles your back and neck have to deal with. While still maintaing a proper an comfortable balance ratio.
This is about the best explanation I can give verbally.
1.) Hold the cue where you want it with your back hand.
2.) Place that hand at the side of your hip….back side of the hand on the side seam.
3.) Now place your bridge hand on the shaft
4.) Step up to the shot and look through the cue ball and sight the contact point…while standing and your going to be somewhere around that 45 degree angle in relation to that shot. No argueing semantics if its 30 degrees or 60 its an angular position lets just say that.
5.) Now RAISE your bridge hand up to in front your face arm extended.
6.) Sight that line through the shaft, its an optical illusion that you can see through the cue shaft at the cue ball and object ball and pocket.
7.) Then step into the shot…placing the bridge hand down so the tip drops almost touching the ball.
You do this without taking your back hand off that jeans pocket and seam.
8.) As you drop down your almost at a 90 degree angle so spread your stance to get comfortable…..just take a lil’ step back till its comfortable but maintain that forward balance....along with some knee bend it fixes itself. And your back ain't gonna feel wacked out
9.) Relax your body and watch what your rear hand does….it pops off the hip and falls naturally into alignment with the shot along with the eyes and feet.
I’m very much going to try and put up some photo stills you can see the steps.
It is so simple and easy to duplicate its amazing, a great way to teach and understand but like you guys said, its hard with words.
Eventually you develop your own style but its a wonderful, basic system, to get you started in the right direction.
