I was wondering this, too. On vertical axis hits, I was not getting the accuracy out of my 314. A traditional solid maple shaft worked well and I picked up a carbon shaft that also delivers. I don't know what factors are affecting this. If my stroke was crooked, I would expect an LD shaft to be less inaccurate, unless my understanding of deflection doesn't apply. I don't see how my technique on vertical axis shots works better with a stiffer shaft. I don't know if the tip, assuming it's not misshapen would cause this. I don't think the placebo effect is that important because I didn't remember what shaft I was using until I dogged a bunch of shots. I do know that those "maybe" shots are "fighting chance" with the stiffer shafts and "what made you think that was a good idea?" with the more flexible shafts.
