By your message, 'bow arch' becomes clear gradually.

I guess typical 'bow arch' is old type rotational method. Hitters are Williams, Dimaggio, Mantle and so on.
Extension of front leg and backward movement of front shoulder occur, and generated energy is transferred through the bottom hand to the bat.
(bottom hand flail)
Mantle's form can be seen here.

Two types which I mentioned in the message Oct 18 are different from 'bow arch'.
It may be said that typeA is 'arch bow arch' and typeB is 'arch bow'.

Bonds is typeA and Garciaparra is typeB

Both types pull the bat with top hand using abs. Therefore 'bow' occurs.
Because Bonds pull the bat backward with top hand before contact, 'arch' is added. The barrel of the bat is accelerated by forward movement of center of gravity of the bat and backward force applied by top hand.(top hand flail). It's like whip or fly fishing and not push-pull torque.

Thank you
