I too like a full splice but here is a bit of food for thought.
What can be more 'solid' than a one piece butt made of solid wood?
When Bob Meucci was testing cues for his Black Dot shaft comparisons, he did the stock hit with a Adam Balabushka made by Richard Helmstetter who later went on to Callaway Golf Fame.
The cue hot with rather little deflection or squirt. He commented that is must be a very well made BUTT. He did so because he knew that it could not be because of the stock 13mm shaft.
Meucci now has what he calls the Power Piston Butt.
Just some food for though about what the 'solid hit' may actually really be about.
Best Wishes to All.
PS I was playing with a Helmstetter Balabuska before I ever saw that video.
