Im a total heel.

The vessel with the pestle has the brew that is true!
pick up or pivot
Three more questions: regardless of whether you turn through the heel, whole foot, or toes,
- do you pick up your feet when you turn, or do you constantly make contact with the ground?
- Do you turn one foot before the other, or simultaneously?
- does the power in the turn originate from the feet, or the waist?
Me- I turn through the heels
- pick up
- one before other
- feet first, then waist.
I try to shift on the K1/Bubbling well point located just behind the ball of the foot and before the arch begins. IMO shifting should go into the opponent’s CoG to disrupt his structure and balance.
When you stand normally, the CoG is directly supported over the middle of the feet. When the knees are bent and you sink down, the CoG shifts forward slightly to maintain stability. This point is the K1.
When I shift, I want to maintain that stability so that I can use the ground to help redirect the force. Without the ground, I am in danger of being uprooted. Shifting on the heels moves the weight and CoG slightly back and breaks the connection between the feet and the ground. Shifting on the toes brings the CoG too far forward.

heels
We are taught to to use heels, like a winshield wiper. I am used to executing it via middle, but I’m exploring the “heel” use now.

Then you don’t understand the idea behind turning on the heels. there are good explanations available … maybe even on your own website.
I agree with what dzu says with regards to the body COG, but it is also important to note that when you stand naturally, about 60% of the body weight is taken by the heels and 40% by the balls of the feet. Therefore by changing into the wing chun stance with bent knees etc. the weight tends to more evenly distributed between forefoot and rearfoot. Hence the whole foot should be used to maintain that distribution.

Where are there good explanations?
Use just your heels to turn and you are NOT balanced. A good Wing Chun man will take your balance as you have already contributed to giving it up. Why help your opponent with bad structure?
You want to have the body weight over the arch of the foot. I think Dzu was mentioning the details, or something similar to our approach, but in any case you should not be just using either the heel or the toes alone.
Doing so means you do not have balance. You are either going backwards (heels) or going forward (toes).
Is it harder to develop that skill? Sure. But that’s why it is Kung fu after all.
Heels, I did train with an instructor that pivoted on the toes but I didn’t like it, I felt it makes you unbalanced.
“Is it harder to develop that skill? Sure.”
It is harder to develop balance from pivoting on the heels. (“But that’s why it is Kung fu after all”)
I experimented. Try doing a turning punching on your toes and hitting a wallbag. You’ll get pushed back onto your heels, and the punch will be weak.
Do it on the whole foot/heels, and it’s a differnt story, more powerful, and your COG stays the same, and force goes into the punch.
Cool
All i wanted was some RICE CAKES! Now? WE MUST BATTLE.
There are too many factors to consider… punching a wall and trying it just isn’t enough…
