Nike Sumo2 driver review
Sumo 2 offers stability

Just like the wrestlers of the same name, the first thing you notice about the Nike SasQuatch SUMO 2 driver, is its size - about 13 cms wide and deep (that's 25 square inches in old money) - equivalent to the crust of an average Supermarket thick-sliced loaf.

Get the picture?

The second thing is the sound it makes - unlike anything else I've ever hit. The sound made by the original Callaway metal-headed drivers (Big and Biggest Berthas) in the late 1980s was distinctive but the Nike Sumo 2 sets your ears ringing and heads of other golfers within 50 yards, turning.

'Clink', 'Tink', 'Boing' or 'Doing' doesn't really do it justice. Give your average central heating radiator a tap with a claw hammer and you're closer to reproducing the sounds of a modern golf ball on this club's titanium face.

Address the ball and it dwarfs it but I can imagine it instilling huge confidence into those nervous, inexperienced golfers among us, worried that we might not make contact with the ball off the tee. Surely, with this club you can't miss!

As described above, SUMO 2 stands for SUper MOment of Inertia Squared, the technical term within club-making that identifies how the club is delivered squarely to the ball at impact. A high MOI, we're told, prevents the shaft and clubhead twisting as it makes contact with the ball to send it off line.

In other words, the Nike SUMO 2 with its square shape, has enabled engineers to redistribute and reposition weight into the corners of the club head (manufacturers are restricted to a maximum volume of 460cc) for added stability.

Put another way, imagine a clubhead as a circular bread roll of 460 cc - press down on it and it's still a 460 cc bread roll but its shape has changed. Consequently the SUMO 2's face is wider but less deep than other modern drivers making it more forgiving when the ball is hit off the toe or heel but making contact with the ball, higher or lower on the clubface more critical.

For those looking for added length, don't expect to find it immediately in the SUMO 2. However, this club will give you confidence to hit the ball harder and should help straighten out those wild drivers for whom length isn't a problem - but direction is.

An added bonus is the fact that off the deck the SUMO 2 is awesome. I encouraged two of my playing partners to try it, who had never previously had the confidence to hit a ball off the fairway with a driver and they were amazed at the results - a penetrating left-to right flight with lots of roll.

The Golfmagic Verdict
Rating: 8/10
Summary: If you're already a straight hitter, I doubt the SUMO 2 will deliver more length to your established accuracy. However, if you've got 300 quid to spare and the opportunity to add control and accuracy to your already prodigious length, its music to your ears (and you don't mind outrageous sound effects), then this square phenomenon is for you.

A few days ago (today's date is 27/03/07), I heard the disturbing news from one of our local professionals that the new Nike Sumo square headed driver has been deemed illegal by the R&A, (although I suspect it is more probably the USGA), on the grounds that the COR rating is to high.

This includes drivers being used by professionals on tour.

He added that all Nike square headed drivers were being recalled.

Everyone who has bought one of these, (including you Tiger), ought to contact your supplier.

If anyone else has any news, in addition or to the contrary, please by all means post it.

This does't surprise me at all. When manufacturers push the limits they will inevitably cross the line at some point.
Apparently a competitor blew Nike up to the USGA, I bet Nike will out there testing every elses drivers from now on.

At least Nike are doing the honourable thing and replacing everyones new driver.

From what I read and hear they won't have replace too many though.....

Shanker but there are a few things that are wrong about the statement the pro gave you. Although the driver is illegal it was the Characteristic Time (CT) that was the failure point, although this does have some correlation to the COR.

Also it does not include the tour drivers (as stated in the Nike press release) as they are not the same as the reatil version and have been proven to be fine.

That being the case BT@Home, perhaps it is a good thing that it is now a little more in the open that the general public get the production line stuff that isn't monitored as closely as the gear the pro's get to play with.

I think we have long suspected and indeed been aware that they get to play with kit we can only dream about, equipment that isn't released or made available to us.

This goes not only for golf clubs, along with shafts of course!), but also balls. Take the ProV1 for instance, how many perfectly balanced balls are there in a box of 12 - not many I'll bet.

The top pro's play with a totally different product to what we are offered.

Does everyone think that is right?

Not always, there are certain websites that make a lot of money from selling "tour" kit, which is actually not so special. You can buy Taylormade TP gear, but some will have you think that its different from the actual tour gear that the pros use (no real proof to say that it is, except that the pro gear will have been specifically taylored for that pro).

In terms of irons, i hear an awful lot of pro use special/one-off forgings with sponsor logos on them. Also there is the Nike/Bridgestone ball idea that is usually floated around aswell.

To be honest i believe that 90% of pros simply used custom fitted items, specially selected for them.

The pro using different kit is a myth that has been in previous threads... Unfortunately there are no bands of monks slaving away in a hot forge making clubs out of meteors.
They spend ages on launch monitors getting the exact lofts, shafts and clubs bent to their liking. As you can read about Luke Donald on this site he uses mp32's but has the sole ground for him by the tour van.
I suspect that maybe it wasn't all the clubs that are wrong but it's easier to recall the whole batch... after all it's not easy to test the cor of everyone's driver to see if you are in the bad category, easier just to replace it.
