You can attach the lead via the Speed Link if you wish. All you need do is splice a Speed Link to the lead core. Here you can see the splicing needle threaded through the end of 35lb Green Fox Lead Core with some of the lead core removed. The Speed Link is placed on the free end of the braid outer.
The tag is then picked up in the lip of the splicing needle and drawn through the centre of the braid to emerge as shown. Trim away the spare and smooth out the braid. The Speed Link is now neatly spliced into the end of your lead core. Thread the Helicopter Bead onto your main line and join the lead core to main line with the knot described above.
