Excellent read. The excerpt below is exactly what I was dealing with as far as boot fit.
"When product development authority David Bertoni was international marketing manager for Salomon bindings in the mid-90’s, he conducted a wide-ranging study of ramp angle, known in binding engineering circles as delta. The particular ramp angle he examined wasn’t created by raising the heel in the boot but by adding shims between the ski and binding. The study showed that among men there were very different needs and desires for less or more ramp angle depending on the skier’s activity/arena. Mogul skiers, for example, had to have more ramp angle for their event; it didn’t matter if the heel position compromised edging at the bottom of the turn because most mogul skiers never finish a turn. Downhill racers had exactly the opposite requirement; without a lower heel to apply pressure past the turn apex, racers don’t finish the course, period. Recreational men were somewhere in between, making the overall picture complicated.
The women’s results were so different from men’s that Bertoni recalls he found them “startling.” Every woman in the study, from Olympian to terminal intermediate, felt more comfort and control when raised 5mm to 15mm higher in the heel. While Bertoni’s delta study didn’t examine increasing heel elevation in the boot, he believes that any change in the angle of the foot relative to the ski, however it’s accomplished, will reposition a woman’s center of mass forward, towards the ball of the foot. If the increase in heel height is effected inside the boot, it will have the multiple benefits of raising the calf slightly out of the boot, increasing leverage over the tongue and raising the ankle relative to the cuff pivot, all of which help the woman achieve a comfortable, balanced athletic position. Bertoni compares it to the body positioning a point guard assumes when an opponent with the ball is bearing down, on the balls of the feet, ready to go in any direction.
Pressed to further illuminate what was meant by “comfort and control,” Bertoni expounded. “In the end, it’s a balance issue. The women felt stronger and more agile because they were in a better, balanced position. The reason is, by raising the woman’s heel relative to the ski she achieves a mechanical advantage over the boot she doesn’t have in the lower position.”
One possible stance “correction” Bertoni counsels against is increasing the forward lean angle of the upper cuff. “The more you increase forward inclination, the more the butt drops and weight shifts rearward,” he notes, or exactly the opposite of the intended effect."

). I've since switched to G3 Ion bindings with lower angle and that has helped me be more centered.
