Streamline Galaxy hooks are first hand cast with a cosmetic-quality resin and resin-based pigments and then turned and carved to the ergonomic Streamline shape. All Streamline Galaxy hooks have their size engraved on the body of the hook just like the wooden Streamlines. Also they have the same length, width, and ergonomic proportions as the wooden Streamlines. The resin Streamlines are 0.2 - 0.3 oz heavier than the wooden Streamlines. For comparison, a wooden Streamline is 0.5 oz, a resin Streamline is 0.75 oz, and an Odyssey is 1.5 oz.
