have characteristics, such as more flexible tips, which yield
more distances, but pooler accuracy. Consistent with Whitaker’s
need for providing shafts having differing flexibilities for
given ball striking range potentials (column 2, lines 58-67),
Pompa teaches at column 2, line 62 to column 3, line 15 that:
The bottom end 22 of the upper composite butt section
14 is reduced in diameter, to telescopingly and slidingly
fit into the inside wall of the elongated last step 26 of
lower metallic tip section 12. It is bonded therein with
high strength epoxy adhesive 24, as shown in FIG. 2. The
length of the bonded section is denoted in FIG. 1 by
dimension C and, in practice, is about 1_ inches. The
junction shoulder 20, between lower metallic tip section 12
and upper composite butt section 14, is smooth and flush.
From that point, the upper composite butt section 14 tapers
progressively and outwardly to a standard butt diameter as
its top end 28. Using the standard 43 inch driver
previously mentioned as an example, it may been seen that
the proportion of the length of the lower metallic tip
section 12 and the upper composition butt section 14, to
total shaft length, denoted by dimension A in FIG. 1, is on
the order of one-third and two-thirds respectively. This
