I know that you probably will not want to hear what i am about to post but here is my 2 cents.
Get a different Cu.
Look for one with close to 600 hps and 600+ strength. I prefer a Cu with no resist greater than 80.
Why - if he is to solo tough stuff you need 700+ Hps. With yours you would need to waste 60x3 = 180 training points just to get to 600.
If it is a very rare color then it might be worth training.
