Carl, as always, you're so brave to step forward like this!
The only thing I could think of becoming a problem was if you had a little grit in your strop, your chance of hitting it with the same bit of blade over and over and over is a little greater than if you were doing a true X stroke. Kinda like that lawn I once had, where I wore ruts with the mower wheels because I never varied my mowing pattern. Man, that was such a metaphor for my life at the time. It still haunts me sometimes. That's why I ALWAYS do X strokes, and why I'll never buy a 3" strop and face that risk of back and forth, back and forth, no need or reason to vary. Been there, done that, have the nightmares.
BTW, I knew what you were talking about right away. Just goes to show what soul-brothers we are, man. <fist bump>
