The tungsten drop shot weight works great on hard bottoms. The presentation of the lure gains extra appeal as it rolls, enticing the predators to snap.
But the most important thing is: fish with what you believe in and trust! Trust in your rig and lure will usually bring you more fish than all the advice in the world. Nature remains unpredictable. Fortunately!
Tungsten has a higher density than lead and is therefore many times smaller. Due to the reduced air and water resistance, longer casting distances and faster sinking phases can be achieved.
