CG isn't one exact spot, it's a pretty wide range on a plane that size,, I agree that balance point seems a little aft,, but if you like the way it flies there,, leave it, I tend to set up my aerobatic planes with an aft CG,, just the way I like it too.
p.s.
I cant tell where they are, I assume they are all the way forward in the motor box,, but I would move my batteries up to the stand offs before I start adding weight
good luck
