THAT'S IT CUB, Al T has never had original though in his little head in his entire life  I mean, god, every time he bends his elbow his mouth opens.

I lean toward Al's way of thinking. Does that mean I'm drinking too much?
;-(
It's breaking a quarter inch above the hosel. Yep, epoxy up in the shaft can
cause it to break but what makes me think this isn't it is the statement
"they keep breaking". That insinuates multiple occurrences. Unless the
clubmaker is an idiot, I doubt that excess epoxy is a continuing problem.
Surely a competitor would choose a clubmaker based on good reputation. The
problem sounds more related to the impact because it is repeated. I imagine
that the shaft is an ultralight, making Al's theory even more plausable.
Check the impact on the face with some painter's tape. If that's not it,
look for excess epoxy in the broken shafts. If that's still not it, go with
a fiber wound shaft. Of course the weight goes up but at least it will be
less than steel.
FWIW
