he changes cue on a regular basis?!!
i would probably not say on a 'regular' basis but, yes he changes it up.
Think about it. For one he is not that long with the longer cue in comparison.
The longer cue can be good for your stroke for normal shots but can make finesse shots a bit more antsy.
The table is not the same in the beginning as it is at the end of each day.
Golfers are allowed 14 clubs because every shot is not the same.
Pool players now have break & jump cues. That was not always the case.
Earl is older, but has said that he could never go back to a regular length cue.
I have 29" & 30" OB shafts & that one inch does make a difference.
That said I also have a Cuetec break/jump cue that has a 6" butt extension & the difference is just that different than adding even that 1" to the front of the cue.
Sometimes a change just increases one's focus.
I'm not sure nor really have any idea as to why he made the change, but I'm sure that he had his reason(s).
Best 2 You & All.
