Hi guys, looking to fish farmoor in a couple of weeks time so will probably use a booby form time to time. I have just read in trout fisherman (jan - feb edition) a special knotm that is supposed to allow the booby more movement on the retrieve?
Does anyone use these?
I am a little confused as tying the knot it doesn't appear to move anymore? I am aware of knots used for plugs and lures but they don't pull tight to the eye as this one does? hope that makes sense would appreciate your thoughts

p.s anyone fished farmoor recently
