I hadn't thought of using both hands while shaving until I opted to try a srt8. I watched Lynn's DVD several times and poked around here for some time and picked up that using both was recommended.
When I 1st started using a str8, using the left hand felt odd but quickly became 2nd nature. Now I can't imagine how I would be able to maintain proper angles and see what I'm doing using just the right hand.
Right on the right side WTG, left on the left WTG. For the chin, near the adams-apple and under the nose, I use just my right. I finish up by using opposing hands for ATG on the cheeks (left hand shaving upward on the right cheek and vice-versa).
Only place I still haven't figured out is how to hold a proper angle with either hand and try to shave along the jaw line. I need to get closer by shaving from the back of the jaw toward the chin but I just can't seem to contort into the right position! Time and patience......
