Beginner Help Please

I am on my 4th SR shave and liking every minutes. I still have not gotten as smooth as shave as with my DE - but very close and some places even better. My specific problem is: At my neck and at my chin line. My beard on my neck and chin line grows on an angle from outside of the neck to the center of my neck. I can shave going from the base of the neck to the chin, but have no idea on how to shave from the center of the neck to the outside of the neck. This is an ATG pass. I have checked posted videos and can't find one that does this.. I am fine WTG and fine XTG and even can do ATG on my cheeks, but can't figure the correct way to get the ATG (my grain) on the neck. Any help is appreciated. I have noticed that my WTG is a closer shave than the DE. I am still having resistance of my beard against the razor which is higher than my DE - but then again there is more bland area engaging the beard, so I expect the resistance would be higher.
Thanks for all your help in advance and I am looking forward to my next SR shave.

I can not get a true ATG on my windpipe, so I do lots of diagonal attacks. Scything motion can help as well. Once you can clear the chin:
Turn the razor upside down
tuck your chin to your shoulder
pull up the skin from your cheek toward your eye.
(these will make a flat area to shave)
use the razor to go from esophagus to ear.

thanks for the insight

also for me, dont watch the blade here, use feel. if you can use BOTH hands, left side right hand - right side left hand, and shave toward center and up with a slight scything motion you will achieve. careful also, as this is where when i used too much pressure i did get ingrown hairs. patience. and really try to start using the full blade in your pass, it will help accomplish what your looking for.
