Yes, I have heard L stance and back stance used synonymously although I suspect weighting is different. I watch a video of Dan-Gun and I think we are back to semantics. I see the knife hand moves you mention and we use them in various forms but I have never seen a spear hand in back stance. I don't see how the mechanics would work.Is a back stance the same as an L stance?
If so, in the Dan-Gun pattern there are knifehand guarding blocks (moves 1 and 3) and knifehand strikes (moves 18 and 20) in L stance.
There are more instances of the same (and different) knifehand techniques in other patterns too, which I can cite if you like?
