In a semi-squat position, I have the pins set just about an inch or so above the knees. My other position is about 3/4's up the thighs, when in that semi-squat position. Having the pins set below the knee position allows too much stress on the lower back (leaning forward,out of alinement with the hip/back lifting position) for me. I''m 6'2. I get 150+ above any other pin settings from the 3/4's pin settings, which is really the whole point of lifting max weight for partial reps. Doing 950+, with straps, is my present pull from that 2 to 3 inch pin position (3/4's) to top standing position. Good luck.
