The Dahlia 75 has much larger weights than the D55 with slightly more aggressive airfoils! It has an amazingly long flight for a wood boomerang and takes 12 seconds to complete its flight. You won't believe your eyes! The Dahlia 75 takes a very precise throw that is almost flat and more into the wind than other recreational boomerangs. Experience with other hooks is highly recommended as well as a field that is at least the size of 2 soccer fields with no obstructions.
