Dale,
That looks like a solid lineup. I have not thrown the Charcoal but I do have two Violet Gargoyles and anything outside of a flood or a drought I can play them on and have had huge success with them. I am a easy flowin' down and in guy and can send you photos of my layouts so you can get a better idea of how I play if it interests you. Personally, I think the Violet Gargoyle would be a good addition as a Medium Oil ball. Even though they call it a mid-priced ball, it has the power to get the results of the high end equipment, bar none.
