This is an interesting topic. In the few times where I swung really well there is no question the weight is on my right heel but most of the time I don't and I feel "wobbly" on top of swing. Two of my golf buddies actually have a noticeable right heel-lift on top of swing. Both are natural athletes (hcpd about 10) so I wasn't sure if "weight on right heel" is a necessity (I assumed natural athletes would likely, naturally, gets to optimal positions). Interesting to see what Brian or other instructors has to say on the subject.
