Well, brother, you are definitely going to get some opinions on this.
As practiced for utility, I think it sounds like a great self defense program.
As a static embodiment of Goju, it may be lacking somewhat. However, if I remember correctly, wasn't Goju a combination of different arts to begin with? I think that by keeping the art functional, you guys are very well keeping to the values of what Miyagi (sp?) had in mind.
However, if you are trying to maintain the style of Goju, you may find others not as accepting. Depends on what you want out of the art.
