It's all down to what you want, like any engineering project. The outcome will can only be as good as the specification.
You specify what you want, unless you have a 'customer'
Do you want max performance in terms of speed, smoothness or maybe you want max weirdness or maybe just max fun.
It's all down to you, of course most staves are some sort of compromise.
You may just say I want the best possible bow from this stave, but unless you specify what you mean by 'best' it is meaningless.
Personally I would go for best speed/shootability even if it means straightening, unless a stave is absolutely crying out to be a character bow!
In which case I'd go for max weirdness and beauty and not really worry how well it shoots (ok it's gotta actually throw an arrow, but it becomes a sculpture rather than a working bow...(IMO)
Of course engineering and beauty often go hand in hand...if it looks right it probably is right.
I shall sumarize by saying you should stop thinkin' and a worryin' and get back to makin' bows
