The Elite Composite Series of Dual Helix with uni-directional fiberglass blanks are three ply, dual helix build with carbon fiber and then an additional ply making use of uni-directional fiberglass. The exceptional lift these rods attain is a result of the uni-directional glass (UC is the only firm using this unique fiberglass in their build). Dual Helix construction provides the hoop strength, and glass provides the lift. Other manufacturers use dual oriented glass to gain hoop strength at a lesser degree than UC accomplishes.
