PROTO is a driver for professional golfers under HONMA contract.
There is no star mark on the shaft, but of course it is 5 stars.
The shaft color is custom-ordered purple and is very rare.
The head is a 3 star head.
Most Honma tour pros don't use 5 star heads.
Because the 5star head is close to a Hi-Cor head,
it may break when used by tour pros.
So they use 3star or PROTO head.
Enjoy the best HONMA shafts.
The shaft alone is worth $2500.
