Takayama Scorpion intended use?

So I've owned a takayama Scorpion Series 1 for a few years. In many ways it works well where I surf (mostly very weak very short period waves). But I've always wondered about that tail. It seems really pinny for small waves. What would you say is the type of wave it is truly intended for, and why?

(I'm considering trading it in for something with a slightly wider tail but a slightly more aggressive nose)

The board in the photo is not mine but mine is similar. (Mine is a 6'4, this is a 7')
