I was under the impression people would post their swings in the Member Swings forum to get free advice and take the nuggets you like and forgot the rest realizing the intentions are good, at least I find that enjoyable. I apologize if I offended you or anyone else that was not my intentions. I have studied the golf swing quite a bit, but in no way a Master and do not claim to be and probably never will be. Relatively speaking I am a very good player and getting to where I am now was through trial n error, reading countless articles, discussing ideas with Instructors and more importantly not being afraid to be wrong, which I often am =) and to learn from mistakes n turn them into wisdom. I think I saw that on a bumper sticker.
I didn't tell anyone to do anything nor would I unless it was to prevent someone from hurting someone else, but I did make a suggestion and the rest is in the air to grab if you want it. And the advice I gave in regards to lunging in transition/head moving past the ball thru impact is directly related to 1 of the issues Wanzo said he was working on. Even if I provided free advice that wasn't related I do not see the harm.
In regards to the feet and knees together drill that has been around since the beginning of golf. I've never heard any instructor say that drill could be detrimental or retard someone's progress. Some drills are like vitamins, even if they don't wildly advance your health its still worthwhile to take the vitamins since they have been known to help so many and no evidence that they have hurt anyone. That drill typically gives players the feeling of how much the arms actually do in the swing and greatly improves body awareness, at least that's my opinion.
Looks like you made good improvement just from Dec. 20 - Jan 2nd. That's awesome if it has been getting better so quickly. Keep up the good work.
