The main characteristic of the Helter Twister is that it resembles a school of small or juvenile fish swimming in the middle layer of clear water. 

At Its inception, the designers at Imakatsu were aiming for a spinnerbait with high anti-cover avoidance.
Once they discovered that it could be used as an "aggregate lure," akin to an Alabama rig, the design quickly changed. Bass are more likely to target a school of fish rather than a single fish swimming alone.

The Helter Twister's ability to attract fish is high because it’s designed to look like a weaker school of small fish, with thinner blades and weaker vibration than typical Alabama rigs.

Another notable point of the Helter Twister is that when it falls, it looks like a school of small fish escaping from a predator by diving into gaps such as rocks. While other spinnerbaits may curve and fall, the Helter Twister drops vertically, earning the move the title ‘Osprey Fall’, because it resembles the US military’s Osprey Helicopter. The Helter Twister was originally designed to be difficult to snag, so it’s possible to approach obstacles with confidence, and entice hiding Bass to strike.

You can add or remove blades to further enhance the effect of the 4 wire Alabama-type rig. One such customization is adding the G-nius Project Plus Blade Special Blade System, a spinnerbait arm add-on that Dr. Aoki produced and sold as an artificial bait enhancement. Mr. Imae, the developer, says that it matches well to the Helter Twister. 

The Helter Twister also has a chin rig hanger that is not found in other spinnerbaits, to set weight on the nose (ex: Quick Changer- VARIVAS) for adjusting diving depth to go after really deep fish.
