Four Sons of Horus Options

Has anyone here used the four sons of Horus (Egyptian funerary deities) in ritual to represent the cardinal points? I am a bit amazed as to how many different correspondences to directions or elements can determined.

In the classical Egyptian we have the following:

Ahephi = North

Ameshet = South

Tmoumathph = East

Kabehsnuf = West

Not counting the golden dawn attributions (which seem to me inaccurate due to incorrect assignment of organs) , I have come across several other methods during my research.

I find the most success when using the historical system in my practice. I am curious as to the experiences of others using these deities. If you use another system of correspondences what was the basis of your choice to do so?

qebhsenuef is one of the sons of horus i am on good terms with.

he came to me during a severe stomach infection and ever since, i have kept his (national geographic magazine pic) image in a heavy wooden frame above the fridge, and i have never had issues ever again... not even when others get sick from eating the same bad food.

i imagine all four of them must be similar in action... perhaps keeping tobacco in a tuamusef container may be advantageous, etcetcetc.
