-Finished spinning Twisto RIGS Wolfram are made of wolfram wire with 15kg breaking strength and high quality treble hook from Mustad. The shortest, 6cm rig has a size 8 treble hook. This type is suitable for smaller lures. Medium length, 10cm rig contains a size 4 treble hook. The longest rig in this series has 12cm and is fitted with hook no. 1. Use wolfram wires wherever there is a risk of biting, eg. by sharp pikes teeth; if you need larger trebles and a longer rig itself. However, you do not need to use Twisto RIGS with other TWISTO products only. Feel free to also upgrade rubber fitted with the classic jig hook BOMB! Package includes 3 pieces.
