You can' t compare these they are not even close in any catergory.
Let me make it easier for you. Take the A-bangs out of the equation. You are too heavy and they will ski like a wet noodle. So if you insist on limiting yourself to these two brands then the Ar7 or ArV will fit the bill.
However consider expanding your options: check out some other manufacturers....Icelandic, Moment, Liberty, ON3P... Basically I recommend you start a new list and include some awesome made in North America skis. If you are not interested in making an effort, then go with the AR7 it is a fantastic product, a do a little of everything ski.
