PTFE Slip Bushes
To play carp correctly, with large diameter elastics over size 10, you need to cut back some pole tips a long way. This prevents them bending too much when you lift to net a fish. If the tip bends too much, the elastic will stick to the inside of the top section. How far you cut back the tip may determine which type of bush you can fit. If you cut it back a long way to make it ultra stiff, the internal diameter of the tip may be too large to fit an internal bush. In this case external is the only option.
Many top anglers remove the number one section and fit an internal or external Stretch Slip Bush straight on to their number 2 section. This produces an ultra stiff tip and guarantees smooth elastic perfromance.
