I tried using the pull buoy as mentioned earlier in the thread -- as Shinji had suggested I should. In about only 20 minutes of continuous push off from the wall, the glide distance with the pull buoy increased by about 10 feet over the distance when I started. Without the pull buoy the glide distance increase was only about 3 feet. This tells me my legs were still lower than desirable and more practice needs to be done. With this practice I can see improvement coming.
If you're not swimming; then you should be skiing......
