Since I bought my Nike vR_s driver, my driving's improved leaps and bounds. My normal shot will go pretty straight, but goes too high (due to hitting off the top of the face) and I know this is losing me some distance.
When I look at my clubface, the ball (nearly 90% of the time), comes off the top middle of the face. It's not that much of an issue as the ball carries well and goes straight, but I know there's obviously a swing flaw here which I'm keen to address to get the extra yardage.
Does anyone know what the likely cause of this might be? Also, is there an easy way to work out if I'm hitting down on the ball or on the upswing?
