In the land that time forgot, 😖 back in the 1990's, I used helicopter rigs quite extensively, and came across a number of problems, one of which was losing fish to hook pulls.
Outurned eyed hooks like current chod hooks was not the answer with pop-ups, the cure was go to inturned eyed hooks like B175's, (or bent hook rigs, now banned) and or stop fishing helicopter set-ups if we used bottom or critically balanced baits.
On most occasions I work on a simple premise:
If I am losing fish to hook pulls, or the hook is right at the edge of the mouth, lengthen the hair.
If I am hooking in the cheek, or the back of the mouth, the hair is too long.
If hooked dead centre perfect.
If not hooking anything, no runs, fishing in the wrong place.
However, regarding hooking, by increasing the amount of free bait by the hookbait, more boilies, more particles or groundbait, can act in the same way as lengthening the hair...
