Lots of helpful advice here! Here is something that made a big difference for me. I paid close attention to the stubble growth pattern below my jawline where I was getting the most irritation. I would change direction as often as needed to ensure my first pass was always WTG. Eventually I could feel where the growth pattern changed and I would make adjustments immediately. Above the jaw is pretty straight forward but below is a swirling mess. Eventually I became satisfied with an efficient 2 pass WTG below the jaw for maximum comfort. Good luck on your journey.
