Would a sniper rather shoot in high wind or low wind? Sure they can accommodate for either, but I bet if asked, they would rather deal with the least amount of variability possible. Unless you simply don't like he feel of an LD shaft, or you are so used to using A regular shaft that you have trouble adjusting, why wouldn't you use one?
I personally don't like the after market LD shafts and my shafts don't deflect too much for me. I use 12mm tips with stiff taper.
I don't shoot any better with a Predator, G Core or OB shaft and I have tried all three, though the predator for a longer period of time. I don't see any need to buy an after market shaft because they are the rage at the moment. There are plenty of good solid maple shafts that have reasonably low deflection and work for me.
If people like the LD aftermarket shafts that's ok. But I don't understand why so many people insist that everyone needs to purchase an aftermarket LD shaft. My feeling is that many of those people just want more people to be like them.
Play with what you like that's all that really matters.
