Neovollic Doubling Set by Neil Kalmanson Price: $58 /pair ; Availability: 1 RH set

This doubling set was made out of Birch plywood. Similar in size and performance to plywood two bladed doublers of the mid 1980s, but with clever artistic shapes.

A wonderful piece of artistic expression from the golden era in American boomeranging. Span = 41 cm ; weight = 174 gm (pair)

Blue*Star G12 Doubling Tri-bladers by Volker Behrens Price: $115/pair ; Availability: 7 RH + 1 LH sets

---

These Doublers are an advanced set of competition boomerangs made out of G12 material. Brightly painted and heavier than the standard Paxolin model, these have better wind resistance and Volker claims that they are nearly unbreakable. The tri-blader with weights and 3 small holes in the hub flies higher and it comes down more quickly. The other tri-blader stays in the air several seconds longer allowing you to catch both with plenty of time to spare. Span = 26 cm ; weight = 104 gm

Günter Möller's "Space Doublers" Price: $55/pair ; Availability: 2 LH Sets

---

This is a pair of tri-bladers used in the doubling event. Made out of 2mm phenolic paper (PERTINAX). For advanced throwers only. Instructions are included. This model requires a harder throw than most doubling sets, but it has better wind resistance as well. Flight distance (weighted) = 24-26 and 27-30m. Thrown at the same time, they separate and return on different flight paths to the thrower. This enables the thrower to catch the Inner Space first and the Outer Space second. This is the technology that Gunter uses when he competes in World Cups! Tip-to-tip Span = 25 cm ; Weight = 84 gm (pair)

Mark Legg's " Nefertiti Doubling Set Trio " Price: $60 ; Availability: 1 LH set

---

This trio of tribladers is exactly what you need in your competition kit for the Doubling event. Made out of 2.4 mm linen phenolic, weighted and drilled with holes and painted bright colors for high visibility, this set is ideal for low to moderate wind conditions. Use the two narrow hub tribladers for most of your catches. Use the "fat hub" model to make your foot catches. Tip-to-tip Span = 25 cm ; Weight = 130 gm (trio)
