Harrison Shotmaker

[gripmyshaft]

I'm trialling one of these tonight after reading about them on WRX. They seem to be revolutionary and the theory is certainly legit too.

For those that dont know, it's a shaft insert that stops the deformation of the graphite just above the tip section. It doesnt increase shaft stiffness, just reduces the deformation in the shaft. Knock on effect is a more stable shaft through impact for all swing types and flexes, reduced spin and more uniform acceleration of the shaft, thus improving accuracy by a huge margin.



Potentially a product that will take the industry by storm and Gamola Golf stock them. I'm also looking at taking these in as a stock item but as with everything I'd like to see it with my own eyes first.

I'll be installing within a Miyazaki Kusala Black 72X that has been tipped 1.5 inches in my own personal R11 9.5 (plays at 44.25 inches)

Visual check first, then I'll get some numbers from the LM if there is any real world difference.

Feel free to discuss and share any experiences or opinions...

Forgot to add, when you spine shafts you are effectively trying to align deformation in the shaft optimally for similar reasons. This product appears to go a step further and make the deformity much more, for want of a better word, uniform.

I think the nature of this product raises a few eyebrows and it takes a bit of outside the box thinking to believe it may work, but the proof is in the pudding with this one, i think Harrison have perhaps struck Oil with this one going on what I've seen so far.

In as professional a manner as possible, I'm rather excited about trying this thing out tonight!

Price?

Price?

USD 140. I'll stick my neck out - it's an awful lot of money for snake oil. 

[gripmyshaft]

Full kit comes in at £97, which i paid for in full from Gamola myself today

If these live up to their already great rep, I'll maybe be able to do them cheaper.

Watch this space...

TM stats with and without are needed methinks

I truly hope they work but can't see how they are not going to undermine other playing characteristics on low kick-point shafts and seems to me that ultimately all they are producing is an expensive  version of the Grafalloy Bi-matrix shaft

I'd like to see some proper data too

Scroll down to the data and pictures. That isn't snake oil.

I'm VERY skeptical of things like these, after all, I research, supply, sell and use high end shaft technology and shafts. If this was snake oil I'd be saying the same myself. There is some very good theory going on here that very few in the industry have done anything about in years, possibly because Harrison patented it and wanted to develop it.

I cant tell you this enough, speed profiling of shafts is absolutely key to hitting good shots with shafts. Something like this doesnt change playing characteristics - it makes something that deforms, deform less. That's a dynamic property that is a weakness in every shaft. This is reducing the extent of that weakness.

This has never been done before, nor has it ever been replicated by shaft design. It's something that simply hasnt been done with shaft construction. Being built into the shaft itself would indeed alter shaft characteristics to a greater extent, that is not what this is doing.

Very flawed approach, but think of it like a retainer for teeth. It's a separate entity that allows the teeth to grow and move in a uniform manner. If you simply had individual retainers for each tooth (build them into each tooth rather than one separate brace) they wouldnt be able to grow, move and develop at the same rate, angle etc.

Uniform flex properties is something ALL shaft manufacturers have been all over since Kim Braly and his old man started frequency matching. None of them have been able to come up with something that works, and this one so far seems to be finding fault with very very few...

I'd suggest a true blind test (easiest with a R9/11 or 910), otherwise I can guarantee results will be as expected.

Two shafts, one with, one without.

Player is handed the club and hits, shaft is changed and hits again, etc. Only the person setting the club knows which is which.

I'll be doing exactly that tonight with a friend. He wont even know there is something different inside the shaft. Only visual mind you, no LM stats tonight, but we will see what happens...

Maybe a silly question, why not just play a stiffer shaft in the first place so it deforms less?

[gripmyshaft]

Shaft flex, or stiffness has nothing to do with how it deforms on impact. We're talking about how the shape of the graphite acts when it's flexed, not the amount of flex on the shaft, or shaft section itself.

This device effectively, in theory, offers someone playing a regular shaft, the deformity he would see when using an X stiff shaft tip, while still allowing him to actually use a regular flex shaft.

I'm suited to an X flex shaft, if I wanted less deformity, like seen in an XX stiff shaft, I'd have to use an XX flex shaft which I wouldnt be able to load or use well at all. The Shotmaker appears to allow the shaft to perform like an X stiff, yet deform like an XX would.

Any clearer?

Not that I'll be buying into this, but an interesting thread from another place...........

As mud!!

I'll see what results others have, then consider parting with my cash....

Are they reusable?
