I’ve tried super hard to make a G425 Thriver work as a draw based tee club that would take out the right side.
At 43.5”, I started with 35g (max available, 26g is “standard”) in the heel. The ball flight was great on 80% of the drives, but I had the occasional double cross hook, and 1-2 tops a round, that I attribute to the swing weight being too light. I tried to work through those bad misses but they were too thorny to not blow up a round.
To add weight, I tried a second weight in the toe (“animal style”) of 7g that felt like the right swing weight, but I hit it to the moon, like an 8i trajectory. It also brought the push fade/slice back into play which was the whole point.
Then I tried lead tape near the front, but too much would reduce the forgiveness a lot and too little would still hit it too the moon.
As someone said above, I think the club just isn’t built to provide a good ball flight at that length. The mini being designed for the 43.75 length, and easier to draw, is a big factor in this equation I think.
