Lag and Power

I brushed off the Skypro the other day since I saw that they had put up Natalie Gulbis' swing. I compared her swing to mine and one thing that really stood out to me as a difference was the wide-narrow-wide in her swing and how mine was basically getting to be narrow-narrow-narrow. I've also been using the swing speed radar to see if there are any changes to speed with the different swing changes that I'm making. Well I was at the range and had three different swings that each hit the ball ok but with different ball flights. One was my current swing, one was really concentrating on rotating through the ball and trying to keep my right elbow bent before impact, and one was going back to the Bradley Hughes swing which I somehow got away from. This last swing gave me the highest swing speed and is probably the most correct one but I didn't have my camera so I couldn't verify!! But after thinking about the swing and looking at pro swings I think it's correct. I don't know how I drifted away from this swing.

It goes back to trying to get more lag speed in my swing. I need to go wide-narrow-wide and find the slot. Then just groove this swing except this time incorporating the other moves that I've since learned such as swinging under plane. Also I'm thinking that before when I was learning this swing I tried to keep my right elbow off my hip like Jim Furyk but this time I'll try to get it more in my belly. I'm hoping this will also help with the right elbow being bent by changing the timing of my swing. Another thing to try differently this time is being flat with this swing like Ben Hogan, last time I was real upright.
