This is my attempt at recreating the SuperSpeed clubs. I'm pretty happy with the result actually.
$45 .00 for the shafts
$17.20 for the grips
$16.50 for the shaft adapters
$20.00 approx. for the various washers I used to match the overall weights.
Roughly AUD$100 all up. So, probably around USD$3.50 if you're not subject to the "Australia tax" .
The actual SuperSpeed clubs are $329.95 on Amazon AU.
