I use the Airflow 40+ lines a lot and sometimes a Teeny Fast sink. Both these are integrated shooting heads. I find I get the best distance with about 4-5 ' of running line outside the tip. But, I have the best accuracy with 2-3 ft out. For loop to loop heads, I try to get the head outside the tip-top fairly gently; here I like ideally 1' of running line out to avoid hingeyness.
We live in complex times, what with fishing,sailing and skiing seasons overlapping.
