Personally myself, I would go with Reflex or Phoenix, they are both great heli sims. I own Reflex and like it a lot but I've read a lot of good thing about the Phoenix sim, they say it's a great heli sim with good support. If I was to buy a new sim it would definitely be Phoenix, I like the idea that you can fly with other people online.
