2010 Kamui 420 vs. 2009 Yamaha 4.6V RPM Tour

Today begins an epic journey for me. Background - Being 5'-3" tall, I have never ever had a driver that wasn't significantly "toe-up" at address. With the materials of today's driver, bending them is a precarious event and thus I have never tried. Since late 2008 I have owned a 2009 Yamaha 4.6V RPM Tour driver, 10* loft, 60* lie with a square face. For more than one-half the time, I have had it shafted with a JPGA Griffin stiff at 45" and D3 swing weight. I have reviewed this driver extensively and quite frankly it is the best I have ever owned in both distance and control.

Enter the 2010 Kamui 420. I ordered this custom head only, non-conforming at 201g, 57* lie, square face, 10.3* loft. I shafted it with another JPGA Griffin shaft at the same specs as the Yamaha.

Time to test. Find time to test. They are calling for 2 feet of snow, so I only have pics and observations to share.

Who knows what this all means other than it may be a tough competition. My goal was to set the Kamui with similar specs as the Yamaha except for the lie of the club. I cannot tell if lofts are exactly the same because I really have no way to measure and the face roll plays games with my eyes. I am excited in the promise a flatter lie may offer me. It seems to me that with a "toe-up" driver position, the effective sweetspot in relation to my swing is small. With a flatter lie, I stand to have better chance of hitting the sweetspot or at least get some forgiveness because hits towards the toe will be higher than a low toe hit on the toe-up driver. Make any sense? Time will tell.

In all pics, Yamaha is on the left (silver on ferrule) and Kamui on the right (black ferrule)

Top address - They look so similar in shape it is hard to tell. This will make adjusting to the Kamui easier.

Face - The Kamui look taller. Measurements confirm this towards the toe. The height to the top of the crown is about 2mm taller.

Front view - Here they really differ. The Kamui tapers more towards the center while the Yamaha maintains the height of the crown more.

Sole - The Kamui has more taper/roll towards the shaft.

Awesome stuff B!

I don't know if it the way you laid out the clubs but in the second pic face on the Kamui does look flatter with toe down.

The Kamui is 3* flatter (if the Yamaha is really 60*). The third pic shows the same as the shafts are set against the same chair at the same angle.

Going to be a great shoot out. Glad to see they both have the same shaft in them.

I think you're going to have a really hard time picking out a clear winner. I'll be surprised if there

is a "hands down" better driver.

Snow sucks

Bogeydog, where in MD do you stay man? I'm in the Temple Hills area! Saw you say 2ft of snow, and thought, "Wait a minute, I'll be getting 2ft of snow too! Where does this guy live?" LOL! Being as you hopefully live close by, I'd love to be present as your assistant, and help you with your testing. :p Seriously though, once I get my KZG stuff put together, I'd really like to play a round with a fellow TourSpec'er. And it'd be cool to see that Kamui in all of it's beautiful glory too. If I can't make testing, I'd love to hear your results as well.

If you play with B and see and try his gear, you soon won't be playing KZG's anymore. (^_^)

Please don't say that gocchin. :( I don't want to go to a life of crime, just to own some of the best equipment on the planet. LOL! I'm sure I'll be able to let go of Bogey's stuff and give it back too him...very slowly, but I'd let it go. :p

Shoutout,

Yes I am in Montgomery County. It is snowing now and I am leaving the office. I haven't heard of a snow wedge so I don't think testing will happen for some time. I will try as soon as I can. PM me and we can work out meeting up sometime. Gocchin is correct - Time to come to the good side!

The Y is right but the company is Yonex.
