You'll get 2 opinions...
You'll get the old "Indian not the arrow" opinion,
Or...
The gotta have it opinion....
Now...as for my opinion, deflection is real. It introduces an element where human error is a risk.
A player needs to judge and compensate for squirt. That's 2 hings...judge and deliver the appropriate amount of compensation for the squirt.
Now, I agree that as a player, you'll need to compensate SOME, even with LD, since it still has deflection...I still say the odds are mathematically IN YOUR FAVOR that you'll make the shot with LD shaft vs a higher deflection shaft.
The more you have to compensate for deflection, the more room for error.
The only reason that I can think of for someone NOT TO USE LD shafts are:
Cost
Tradition
Like the hit of solid maple better..(it is a better hit)...better wood in some cases.
Respect and adoration for the cue maker that labored over and designed the original shaft the cue came with
Resistance to change.
So really, it's up to you. Are the 5 points listed above important to you, or mathematical advantage slightly in your favor more important?
Don't wait for someone to make up your mind for you, You just gotta take this one on yourself with out just using popular opinion. Can't go wrong either way, I shoot with 1st generation Predator 314's which have lower deflection than solid maple shafts, but more deflection than their replacement of today, the 314-2. The 1st gen 314's play almost as good as solid maple shafts though.
I find them to be a perfect balance between hit and accuracy.
