Well, based on what I've seen left on the racks all of what you have listed is going to be stronger than what you're throwing now. That's not bad, just something to be aware of.
If you are just starting out I'd look for something with control built in. The spit fire is a good control ball, sure fire looks that way too from what I've seen. The Doom is a skid snap type piece that might be hard for you to control with the revs you have. I don't know much about the columbia balls.
