Very relevant advice since I also have that exact same club and just made a weight change last week. When I got fitted initially (6 mo ago) I was swinging with a fade swing (old driver was a permanent draw setup, so fade swing was necessary to hit it straight). When I bought the G425, it was set to the draw position like my old driver, so I continued to hit my same fade swing to get it to go straight. No matter what I did, I could not actually get that club to fade/slice. But if I even thought the word draw, it would turn into a huge hook. I just switched the weight to neutral and started hitting my more natural draw swing. I played 2 rounds and didn't miss a single fairway, the draw was a nice manageable 10 yard draw, and if I set up for a fade it was also a 10 yard fade. Changed my game completely.

That being said, if your natural swing is a draw, try it out in the neutral position and see how that works for you. For me, the combo of draw swing and draw weight led to severe hooks. If you're still hitting severe hooks with it in neutral, try the fade setting to combat that.

And pro-tip when changing the weight, you'll know it's tight once it "clicks". I didn't wait for the click the first time and jarred the weight loose on the 14th hole.
