Here is what Mica has said about Standard verses Balance Point and Omega shapes:
__________________________
Our original Standard Point and Omega body shapes were designed as 4-string medium scale basses, and for the time (early 70s) were not considered neck heavy balancing at 2:30 on a clock face.
For 5 and 6 string configurations and extended scale lengths these shapes didnt' balance as well. So Mike and I worked out the Balance Point, a shape meant to look very similar to the original shapes, but with the upper horn long enough to balance in 5, 6 or more strings. Typically, these hang between 1:30 and 2:00 (maybe 2:30 on a 36: scale 6-string).
The balance is primarily dictated by where the upper strap holder is. On the Balance Point, it's up much higher than on the Standard Point family of shapes. To make it look right, I had to make the body even wider.

Here is the first Balance Omega:
