Dyanmic Sole Grind aka DSG

Comments on DSG technology found in the new CG15. What is the advantage of DSG over conventional wedges?

The DSG is a special grind done on the sole of the wedge. Beside the standard bounce grind, there is another grinding done on the end of the bounce towards the back.

If you play lots of open face shot, the DSG will benefit you on hard ground/sand. Below is what I extracted from a website,

Dynamic Sole Grind: Two sole surfaces increase versatility - square faced and full shots will play like a standard bounce wedge, open faced shots play like a low bounce wedge

DSG allows for the bounce to be varied by opening or squaring the clubface. Many brands have variations of DSG. There is the C grind and S grind too.

Dynamic Sole Grind works for more experienced wedge players who can play a wide variety of shots with one wedge. Unless one can work the wedge, most would be better off with regular grinds with the full bounce to keep the wedge from digging in too deep.

As reference, here's what the Vokey site has to say:

Overview on Bounce
Bounce serves to help reduce digging as the wedge interacts with the turf or sand at impact by elevating the leading edge slightly off the ground. Or, as Voke is fond of saying, bounce acts similarly to the rudder on a ship if it were turned sideways, helping the sole glide through the turf or sand as it moves through impact.


Measured Bounce v. Effective Bounce
An important distinction to keep in mind when discussing a wedge’s bounce angle is measured versus effective bounce. The effective bounce of the wedge, however, is more representative of how the wedge will perform on the course from both a playability and versatility standpoint. Sole width, camber and relief are all wedge design elements that determine the effective bounce of a wedge. The following chart generally explains each element’s effect on bounce, all other factors being equal:

Element/ Effective v. Measured/ Reason
Sole Width/ Wider sole = More effective bounce/ More bounce surface area
Sole Relief/ More relief = Less effective bounce/ Less bounce surface area
Sole Camber/ More camber = Less effective bounce**/ Reduces the bounce surface area

**In the case of a thin-soled wedge, adding camber may increase the bounce angle.


Fitting for Bounce in Wedges
Wedges are designed with a wide variety of bounce angles and sole shapes to appeal to different playing styles and course conditions. Generally, players with shallow attack angles and more hand action during their wedge shots prefer wedges with less bounce and narrow but more cambered soles, while players with steeper attack angles and less hand action who like to trap the ball at impact often benefit from wedges with more bounce and wider, less cambered soles. These two types of players are commonly referred to as sliders/sweepers and drivers/diggers, respectively.

For the non-Tour golfer who doesn’t have access to a van full of different wedges, Voke has some simple advice: Bounce is your friend. Wedges with a moderate amount of bounce are versatile for golfers who play on a variety of courses with differing turf and sand conditions. Further, most amateur players would benefit from employing more bounce since they typically don’t hit shots as consistently as a Tour professional.

Hmmm... I do not think beginners or intermediates like us will benefit from such special grinds.

Aiyoh...so many things to consider...I buy wedges based on the loft only...and then all else, during game.... leave it to nature and luck...

Besides loft, I also buy based on chio or not chio.

LOFT= Lack Of F***** Talent??

i was told it stand for "Lots of F***** Talent"....haha !!

Bird, people ask for DSG only lah, why must extract out the whole text book on bounce?

Anyway, it's too strong a dose for me....

how about these simple rules of thumb for the rest of us, hackers:

1. have a sand wedge with at least 10 deg (or higher) bounce to play in the sand and rough
2. have another wedge (gap or lob) with low bounce e.g. 6-8 deg to deal with tight lies or aprons

the rest is a matter of technique, isnt it?

Was too tired to explain in simple terms so I just cut and paste the text book according to Bob Vokey.

And you put it very succintly JC. Consider mine as further reading lor..

In my experienced, I find the DSG to be a versatile one

My Cleveland 588 56* which I have it bend to 58* is still a nice scoring club.

I also liked the RTG ( Raw Grind finished...were it rust ) to add spin
