If you're writing a piece for the Boston Pops, the balance is towards one end. If you're writing a piece for a chamber music society, then it's towards another point. I won't make a final answer on that. I think it changes with every piece.
I just had lunch with Slash two days ago. He loves Axl. He holds no grudges towards him. Twenty years of great music wasn't created because of some stupid grudge. That's a shame.
