On those days when bites are hard to come by or when you are getting takes but loosing fish, subtle changes such as making the hair longer or changing the bait size can make a huge difference to your results. By using the different length stops it is easy to lengthen the hair or alternatively change the size of the hookbait from anywhere between 16mm & 24mm without having to tie a new rig - simple! As the shape of the Extenda stops it makes it very difficult for Crayfish to pull them off. In three sizes: Small: 3.5mm Medium: 7.5mm
