I've used this rig for a few years now, - the main reason is apart from being a very efficient method of hooking is that when using pop ups which i tend to most of the time i never seem to hook fish in the scissors anymore which often resulted in a slight amout of damage, they are always hooked in the bottom lip, slightly either side of centre. There is a way of hinging this rig by using snake bite or skin if you wish, it took me a while to figure this one out last year, but it works brilliantly as follows - Firstly you can't go too small with hooks as you need to pass fairly thick material trough the eye 3 times, reducing the thickness of the loop material won't help as it needs to stay as stiff as poss.
Take your snake bite and strip an amount of
material off (this depends on how many winds you use for the knot and the amount of
hinge material you want below the eye, you actually only need a tiny amount to give the hinge effect, only with practice will know exactly how much you need to strip off)
take a lenghth of mono (at least 15lb) and burn a ball on one end,pass the inner braid thro' the eye, then pass the mono thro' leave the ball hanging below the eye at least an inch holding the mono tight along the top of the shank - this is the fiddley bit - knotless knot the braid as you would,
but you should only have the minimum amount
1-2mm is sufficient showing below the eye
before the stiff section starts , this is why you leave the ball end hanging or it would prevent the snake bite passing back thro' the eye, pull the knot tight you now have a knotless knotted hook with a length of mono sticking out towards the bend, thread your sliding ring down the mono and then pass the loose end of mono back thro' the eye, by now this can be a bit of a squeeze but works OK on Carp 'r' us or penetrators down to size 6, now pull the bottom of the bend sticking out of the winds of the knot on the shank until the ball is only 1-2mm from the bottom of the eye, then pass the other end of the mono back thro' the top of the eye, now this bit really is a bit fiddley! pull the end of the mono until the loop is TIGHT to the shank trim off exess to give you about 15 - 20 mm of line protruding out of the bottom off the eye then CAREFULLY burn ,and let the ball shrivell back until about 3mm from the eye, THEN BLOW ON IT QUICK!! pull on the loop which is tight to the shank untill both balls are tight to the eye , giving you the 'D' loop on the back of the shank,
you now have a stiff 'D' Rig with the advantage of a supple hinge at the hook, which aids the hook falling to the bottom off the mouth of the fish, this i've found is very effective when using a counterbalanced pop up, on a 'take' the stiff section will fall vertically upon ejection whilst the pop up rises in the fishes mouth the 'D' will allow the hook to fall helped by the hinge. I can already hear you all saying 'What a pallava' but after a few practices you'll find it dead easy honest, you'll find all your fish hooked in the centre of the lip, - now someone will come back and say they've hooked a fish up the nostril or somthing, anyway give it a go - let me know what you think.
