My Ego7 came with the original cure bolt. I have never in my life chopped or clipped a ball in the stack. I can't ever remember the last time I had a barrel break in my gun. I have put over over 400,000 shots through this gun. A large portion of that is with tournament grade paint. I am not sure why I would ever need the Cure 2, 3, 3+ or 4.
As for not releasing a new guy every year, I might think about picking up a new ego/sls.
