The Strix is the signature model of DCJ (Duncan Crew Japan) member, Kohta Watanabe.
Kohta Watanabe is 2011/2013 EYYC 1A champion and a Duncan Crew Japan member, and the Strix is his new signature model. The diameter is just between that of the Raptor and Echo, the other two models that Kohta throws, and the profile has been widened slightly, giving it a rather wide body for Duncan's full metal lineup.
The wide gap makes mounting string tricks that much easher, but the fit will depend on your hand size and preferences. Nevertheless, the Strix proves to be a strong option for serious string trick players. The side face is designed to accommodate Kohta's favorite top-on style tricks, smooth and concave and without texture. The designs have been lasered onto the outermost edge only.
The more you throw, the easier you'll be able to tell the difference a single gram or millimeter makes in a yo-yo's design. It seems like the Strix was really designed to illustrate these changes in character, and the importance of such attention to detail.
