What pull pattern are you using?

I am assuming S is still the dominant pull pattern, but if you are using I, are you using it 100% of the time and for all distances? I am not collecting this information for any purpose, just curious how the I pattern adoption is going along and what people think of it. S Pattern: Entering close to the median line of the body, then sculling out before beginning the catch. At the catch the hand begins an inward sweep before turning outward somewhere mid torso with the hand underneath the body. The stroke finishes and exits the water on the final outward sweep. See picture. I Pattern: The hand enters wide of the mid line of the body with no scull before the catch. From the catch to the finish is approximately a straight line. The difference between S and I is S has phases in different directions while I tries to maintain a single direction the entire time. lh5.ggpht.com/.../SANY0001.JPG
