Your question is a tough one to answer.
All though there could very well be someone in the World using a combination of these arms on a single Raven One, keep asking on other forums too.
What I can tell you the Graham Phantom is a dream to work with when it comes to ease of settings.
Beyond that the Phantom works very well on the TW Raven, "your ears would love it".
A forth arm you could add to your list is the 10 or 12 inch Davinci Audio Grand Reference.
This arm could very well replace my Phantom next year.
