Ok...so your the first person to bring up speed. Not something I've thought of before. Although, I'm certainly not trying to "skip rocks" across my face, I def will be trying this slowing down idea. I've tried angles and pulling with the neck area...for me, I fire blanks with that. But, the slowing down stuff...good thoughts. Appreciate it!
Absolutely agree that pulling is essential. What's been helping me improve my shaving is not only stretching the skin, but also displacing it as much as possible from it's original location. This is easier to explain using the gonial angle of your jaw as an example. I stretch and pull the skin so far that the hair patch that would normally be in my neck "mounts up" on the jaw, which allows me to shave it very easily.
I've a few stubborn depressions in my neck and the only way I can shave them is by displacing them sideways!
Good luck mate!
