Also Jeff, to give you some perspective of how sensitive DL is, if my loop length is off by even a 1/8"...........I'll see a noticable difference in scores. Sometimes as little as a 1/8" difference is going to make a world of difference in your holding pattern......and in helping you find that spot in your form where you can hold with no tension at all anywhere but your back. That's the spot you want it........not your shoulders, arms, etc......
