RE: CP Pro Simulation
Axe CP in real life is probably the closest you can get out of the models you named. It was designed to directly compete with the Blade CP/P series.
In all honesty, no simulator has even come close to replicating how squirrely and twitchy the Blades are, FS One is the best so far, but even their CP flies so much smoother and more precise than the real thing.
Any heli you fly will give you the basic skills you need, also make sure to practice nose in a LOT on whichever sim models you choose. Thats the hardest to learn using real stick time.
