Controller for Helicopters?

I don't have FSX yet (still waiting for my preorder), so I'm following the forum concerning tweaks and planning for FSX. I've been interested that many are finding the helicopter to be much more realistic and flyable in FSX. Although I've been a simmer since the beginning of FS, I have never really flown helicopters and thought I might like to try it in FSX.My question is regarding controllers for helicopters. I use a CH Products yoke and rudder pedals for my regular flying. I also have an older MS force feedback joystick (not USB, but gameport?) that I haven't used since Combat Flight Simulator.Stupid question time: Can you fly the helicopter via a yoke, or must you use a joystick to do it realistically. I'm a little concerned that my joystick is not USB and I really don't want to risk conflicts any conflicts with my CH Products USB yoke and rudder setup (now that I have it working in the FSX demo).My system specs are below.Thanks in advance for any help.
