We should all be looking to spin the ball around the greens. Which of the current crop of wedges will give us the best chance to do that? If you have read any of my previous research on wedges you will know that friction between the face and the ball plays a huge role, not only in generating spin, but also in lowering trajectory – both vitally important for control.
The most important part of the clubface of any wedge is not the grooves, but the texturing of the flat areas between the grooves. Keep in mind that the primary purpose of grooves is to channel “matter” away from being caught between the flat areas and the ball – they are not in place to create spin. When you look carefully at the flat areas between the grooves of your wedge you should see some fine milling which looks like corduroy to me. Most club manufacturers will mill the clubface of their premium wedges and it makes a massive difference to the control and ball flight.
The idea behind the test was to see which wedge generated the better grip between face and ball. I had four very new 58 degree wedges available for the test:
- Titleist Vokey SM4 with a DG Spinner shaft – conforming grooves with standard mill pattern on face
- Ping Gorge Tour with a DG Spinner shaft – conforming “gorge” grooves with standard mill pattern on face
- Callaway X Series Jaws CC with a stock steel shaft – additional conforming grooves with no apparent milling on face
- TaylorMade ATV with a KBS shaft – conforming grooves with two-way mill pattern on face
You may notice that the wedges had differing shafts – I obviously would have preferred to have had all the clubs built to the exact same specs, but that was not feasible for this test. Apologies to all Cleveland Golf fans – would love to have had a Cleveland wedge in the mix, but did not have a new version. I had four golf professionals each hit four shots with each wedge. All shots were hit off a mat in order to limit friction being interrupted by matter being caught between face and ball. Titleist ProV1 golf balls were used and each shot had to land somewhere between 40 and 60 yards (ideally at 50 yards). The clubface was cleaned often even though it never appeared to need it. The “normalize” feature on TrackMan was off.
Here are the results:
- ATV 7365 rpm average
- Vokey 7210 rpm average
- Gorge 7193 rpm average
- Jaws 7163 rpm average
As you can see the ATV wedge led the way in generating the highest spin of the four – albeit by a slender 2%. If I was a betting man I would have bet the ATV would generate the most spin as I have always loved the two-way milling treatment on the face. I would also have placed the Jaws wedge at the bottom of the pack, as no matter how many groove edges come in contact with the ball, there is way more flat surface area contacting the ball and it should be milled.
If you do take one thing from this research let it be the following: A fresh wedge with a clean, milled clubface will allow you to generate more spin and a lower trajectory – both important factors in controlling your golf ball around the greens.

There is so much complex information out there regarding the Ball Flight Laws – a ten second Google search yields enough confusion to get my head spinning for a month. The “old” or “new” ball flight laws, Dr. Wiren, TrackMan…..who or what should you believe?
In light of Dr. Einstein‘s insightful quote I am going to give this touchy topic my best shot and try to keep it as simple as possible. Please don’t check out! This is important information for any golfer to comprehend, so bear with me and you’ll gain a far better understanding of why your golf ball reacts the way it does.
There are only four factors that influence ball flight when clean (not necessarily solid) contact is made between a golfball and a clubface.
The faster the clubhead travels the further and higher the ball will travel – generally with more spin. Compare a chip (slow speed) with a pitching wedge vs. a full swing (faster speed) with a pitching wedge…simple enough.
Orientation is a fancy term that refers to where the clubface is angled. Keep in mind that the face angles both left or right or up or down – left or right being an open or closed face and the up/down variable (although hopefully never down) referring to the loft imparted at impact (dynamic loft). The face angle largely determines where the ball launches – left or right of the target and at what angle relative to the ground. A good general point to remember is clubface (for the most part) = launch.
Once again the direction the clubhead travels relative to the target line at impact – left or right (clubpath) and up or down (attack angle) – plays a role in determining ball flight. A lesser role than the clubface, but a role nonetheless. A good general point to remember is clubpath (for the most part) = curve.
Centerdness of Contact
This is a big one and something the vast majority of teachers and golfers tend to underestimate. Most golfers strike the ball on the sweet spot far less frequently than they think . I often see golfers that swing for a draw, yet strike for a fade – in other words they have a clubpath that is in to out, yet hit the ball slightly out the heel which leads to a fade. An off center point of contact on the face leads to gear effect, which overrides or reduces the effect the face orientation and clubhead direction have on ball flight. This factor plays a bigger role than most realize – watch out for it. And the best way to do that – a spray of Dr. Scholl’s foot powder.
Here are a few simple factors to understand and remember:
- The ball launches primarily in the direction of the face – varying degrees of up and either left or right.
- Given a centered hit, clubpath leads to curve. With the curve being away from the clubpath.
- Hitting down does not increase spin, and conversely, hitting up does not necessarily reduce spin.
- Heel hits encourage fades or reduce hooks and toe hits encourage draws or reduce slices.
- The more you hit down on the ball, the more you will swing in to out and the more you hit up on the ball the more you will swing out to in.
Now that you’re finished reading shoot back up to the top and read again. This is vital information to assist with your understanding of of how your golf club “communicates” to your golf ball.

There is so much happening at AndrewRiceGolf.com at the moment that I thought this would be an opportune time to let everybody know what’s been happening and what’s coming up….
I have just formed a relationship with Peter Millar for 2013. I am very excited as I approached the company about wearing their line – it has always been a favorite of mine. Look for Peter Millar clothing in all AndrewRiceGolf.com photos and video shoots.
