Dynacraft Variable Launch / Spin Wedges feature two interchangeable inserts: a 3g black anodized aluminum and 17g stainless steel. Where the weight is positioned will change the center of gravity to produce two unique types of shots. With the heavier insert at the bottom of the head, it produces a lower and more forward center of gravity. With the heavier weight at the top of the clubhead, it produces a slightly higher and more rearward center of gravity.
Most golfers understand that a lower center of gravity will create a higher launch angle. However, testing proved that wasn’t always the case. Surprisingly what changed most was the spin rate by as much as 1000 rpms with the higher CG position creating a low spin rate.
The last part of the ball’s flight path is the final descent. In the image below, we can see that the adjustable golf wedge with the weight in the higher and more rearward position will create a flatter (3º) angle of decent, which will allow the ball to release with more roll once it hits the green. In our case here, the roll was 23% greater (and a total distance of 7 yards longer on average) than the same head, but with the weight located in the lower and more forward position. This wouldn’t be a good scenario if one had a hard time holding the green on approach shots. But those who can’t seem to get the ball back to the hole will sure benefit.
The lesson learned by all of this is shifting 14 grams of weight can totally change the initial trajectory, spin, maximum height, landing angle, amount of roll and finally total net distance the ball travels.
Not everyone will benefit with the higher and more rearward position just like not all golfers will like a certain type of ball (distance vs. spin). The VLS wedge gives you that option without having to change the brand of ball that you like the feel of and its’ performance. Make sure to try the head in both position for both full shots as well as little finesse shots around the green in order to find the position which gets you closer to the hole.
