A correctly built Kielwood shaft might not be immersion water proof but it’s pretty resistant to humidity, i.e., moisture.
Me thinks Pia Filler knows not much of what she speaks or else is just huckstering for the carbon fiber shaft industry.
Here’s a observation I think others will attest to. I have never had any of my cues orig. maple shaft warp, bend, curve
or manifest any curvature. My Palmer is over 60 years old with 2 shafts; my Runde is 41 years old w/3 shafts. My TS
is over 20 years old and both shafts are straight as a tautly pulled string. And I’ve lived in different USA locations.
Now about Kielwood, I have 4 shafts from 2 builders and expect I’ll be adding more. I’m fussy about the specs so a lot
of shaft builders can’t build what I want made. If you look around, you’ll generally find what you want and I have. KW
shafts are not brittle, exhibit much lower deflection than maple equivalents, and are much more resistant to warping.
I have played with carbon shafts. I don’t wear a pool glove and never will. I haven’t any need for it and a silky smooth
wood shaft feels great in my closed bridge whereas CF shafts feel like something I’d get at Walmart or Target on a pool
cue selling for $59.99. CF shafts have a unappealing tactile feeling but wood, well, a properly maintained shaft is A+++.
Pia, and I suppose many of her peers. might possibly have sponsor connections that help influence their comments or
might fervently believe what they say. All I know is my experience with KW shafts and how better they play than maple.
