I learned this skill in less than three days (made it on 10-15-08). The first day, I only did a couple of drills with Stacy stopping me with a mat under the bar. The second day, I did more drills and then tried a few with Stacy holding the mat higher so i could try to spin out. The third day, I made it on my second try! I just need to catch in a double under grip now.
