With Enterprise Tackle imitation baits, buoyancy matters more than colour alone. Pop-up Sweetcorn and floating Imitation Hemp serve a different purpose from Sinking Hemp and Sinking Tiger Nut. First decide whether the hookbait should sink, suspend or help balance another bait.
A pop-up does not lift every rig equally
Test your chosen grain with the complete rig in water. Hook weight, any added boilie and extra weighting together determine how the bait behaves. Mega Pop-up Sweetcorn is a larger version; do not assume you can swap it for a smaller grain without testing the balance again.
Hemp on the hook or hair
The imitation hemp has a soft rubber core that accepts the hook. For Sinking Hemp, the description lists both a single grain on the hook and several on a hair. After rigging, check that the hook point remains clear. These are imitation grains for your rig; do not compare them by feed quantity with a bag of real hemp.
