+atk -hp Summer Gaius

Hi, I got this guy today and from what I can gather, the +atk nature sort of saves his not so ideal statline. The optimal build here on this site is the stereotypical brave bow LnD, which is fine I guess, but I just wanted to know if it's worth it..considering I have a +res-atk Klein ready to be finaly sacrificed to the gods. So basically the question is, if anyone has experience with Summer Gaius builds, doesn't necessarily have to be a quad build.
