I go 1.5 inch down from the throat, just out of habit now. If its too tight there, it gets some hammer time from the rubber mallet to help seat all the fivers better so I can bury the needle.
I remember someone getting into it with me in 09 at the Baltimore TCI show while I was splicing at Knot and Ropes booth, we went back and forth for probably a half hour on it. Personally, Im in agreement with warthaug above, the whip is there for security when UNLOADED. The tension of the jacket when loaded will hold it then, whip is just a pair of suspenders while already wearing a belt. I like to try to get my whip over the crossover in a double braid, but in 16 strand it doesn't really matter, just close enough to throat that your not getting into the reduced core area (internal taper). You wanna grab as much fiber under the whip as possible, IMHO.
