My son has a 2007 faded triple pup Gibson Flying V, his shape is like my bass' shape. That is also the size of the Ibanez and the Dean Flying V basses, there is hardly any difference in size among these four.
But possibly you might want to go this way, the boutique V from Gibson?

A Grabber headstock at its widest almost 4" wide, the Flying V bass headstock only about 3 3/4", so the Flying V headstock is altogether a little sleeker and elongated.
