Middle balance

Stance width could be an issue. All too often I see 7 iron stance widths with drivers. The driver is the longest club, thus it's very easy to shift to the trail foot with a narrow stance, and the narrow stance can quickly allow staying on the trail side on the downswing. Check that first.

Right foot flaring is also important. If the trail foot is straight, it's far easier to get weight onto, over, or even to the outside off the trail foot. Say HELLO to a right sided swing. Especially with a narrower stance.

As for weight distribution with the driver, I have a little more on my trail foot at address. HOWEVER, as the club reaches the top, my weight re-centers to get stacked over my low point (not the ball). That low point is about 2 or so inches behind the ball. Again, I want to be stacked over my low point. I like to feel a little more pressure shift with the driver which is why I load a little more on the trail side. That said, on the backswing my weight is on the inside of my trail heel. Not on top, or outside of my trail foot.

With SnT the weight starts more on the lead side, but the detail to understand (for me) is that the low point will be slightly more forward, so I play the ball slightly more forward. Not a lot, maybe a ball or so. A narrower stance with more weight on the lead side will promote a steeper angle of attack. Thus the club will likely come outside in for a nice slice of pizza. LOL.

I want the driver to "land on a runway", not divebomb into the runway.

Obviously there could be setup issues such as squatting too much, or the butt is way out behind, or straight knees with torso overhang, etc, that can promote all kinds of flawed downstream movements.

BTW, when I talk about more weight on my right side at address with the driver, this is something that must be harnessed, otherwise folks will get back into over-shifting. With SnT OR a right-sided setup, both require me to be stacked OVER my prescribed low point, which is NOT the ball...the low point is behind the ball to promote a slightly positive angle of attack. I use a 9* driver so a 10.5* may allow the low point to be slightly closer to the ball, assuming all else is "good".

I like to feel a pressure shift as mentioned because that seems to promote a "more" automatic lower body engagement to rotate down to the ball. That said, I never was a "shift and lift" guy. Thus for those who still fight shift and lift I do not prescribe this approach.

Tom is OK with a pressure shift, but I'm fairly certain he tends to stay away from that notion because he's seen far too many folks get back into shifting and lifting. Thus the SnT 55/45 weight distribution is perfectly fine. In that case, I setup such that my low point is a little more to the right of the ball. The goal is to avoid a negative angle of attack that puts 7 iron spin on a driver shot.

Yes - To be absolutely clear, this is a personalized customization by @GolfLivesMatter in terms of what performs best for him. It is not completely aligned with my teachings, but as I've said my lessons and drills provide the guidelines and set the boundaries, while allowing ample leeway for each individual golfer to infuse and exercise their own uniqueness.

In other words, I do not specifically teach the rearward pressure shift in the takeaway, but there certainly is some tolerance for it provided the swing center and low point do not drift and as long as the weight is favoring the lead side at the top.

Also, seeking to feel a positive AoA with the driver is not part of my instruction.. As I've referenced previously, the Tour average with the driver is actually minus (e.g.: downward) 1.3 degrees - nearly level - and it should feel level to you - but slightly down nonetheless. Some Tour players do have a positive AoA with the driver, but most amateur golfers should refrain from consciously trying to hit up on the ball as efforts to do so can cause swing and contact issues. With everything, though, let your ball striking, distance, and shot shape be your guide.
