Different drivers on the market will have different amounts and types of adjustable weight. Some drivers are going to have sliding tracks where you can take a single weight and move it’s position. Other drivers like the ZX7 MKii from Srixon have weights of different values that can be moved to different areas of the head. By moving this weight around and playing with how much weight is represented with each one can make a big difference in how the head works for your game.

There’s two schools of thought behind moving weight around the head. The first one is to change ball flight bias and the second is to support the consistent strike from a particular player. The first thought to changing flight bias is using the heavier amount of weight to slow down that side of the head. For example, the ZX7 MKii comes with an 8g and a 4g weight. Wherever you put the heavier weight is going to travel slower through impact. Putting it in the toe is going to slow the closure rate of the head, and putting it in the heel side is going to speed up the closure rate. By promoting a higher closure rate, a player can expect a more draw friendly performance as opposed to putting the weight in the heel of the club which will promote more fade friendly performance. The more weight you put towards either side of the head, the more you can affect the flight bias. Srixon offers weights up to 14g.
