I'm going to switch how I string the bow from holding the upper limb with my right hand and the lower limb over my left leg to holding the upper limb with my left hand and the lower limb over my right leg. By next Spring if the "Korean Tiller" moves the other way I'll know it's caused by I string the bow. If the tiller doesn't change, it's caused by how I shoot or it came that way from YMG. (Shooting left handed is not a good option for me.)
At this point, I think in order to somewhat more effectively prove the Korean tiller concept for the laminates, you would have to carefully string and inspect the bow upon initially receiving it. Pull it back facing a mirror. See what it tells you. Because, yes, reverse pressure will take the tilt out anyway. bluelake also makes note of that on the thread I keep referencing.
I will also throw this out here: there is a possibility that a laminate bow coming with a tilt to the left or right may be passed off by a manufacturer as acceptable. But in reality, no such tilt for a laminate should be there. Hate to think that way but it needs to be thrown out here given some of the circumstances I noted above.
I will also say that based on my knowledge of materials such as that of traditional horn, wood, and sinew gak-gung vs the rigidness of laminate gungs, I somewhat doubt that any laminate is meant to tolerate a set in tilt by the manufacture due to the very rigid, very consistent nature of fiber glass.
But I'm just thinking critically at this point.
