After viewing a video from an experienced SRP member on YouTube, I have done some experimenting with holding my razor with the scales straight out from the blade for some strokes. This is mainly in some of the tighter spots on my chin, at one corner of my mouth where there's a funny sort of bump nearby, and on the scything, upward strokes on my neck. It's less elegant-feeling than the three-finger, right-angle hold but I feel a lot more in control.
