Yeah, this is almost the modern take of this classic rig, however using a light line hair from the bend of the hook, without the hair being a continuation of the hooklink which seems to make it stiffer, the light, long hair makes the point of the hook "heavy" and the hook is more unstable on ejection. Its similar to the very early hairs during their inception with lenny middleton the knotless knot/continuation of hooklink-hair is a relatively recent concept, the hairs were often lighter hairs tied seperatley on to the eye or shank of the hook. As the hooklink of the time was mono, dental floss hairs on mono links were one of the first hair rigs i ever used in the mid 90's
The "hook bend hair" is relatively forgotten about as being "old" but it can work. It looks pretty "hookable" i think with a curveshanked hook, this would flip over and dig in really well.
