I'd suggest compromising and go with a 7.5 foot plow.  Our tractor/loaders are similar in size in weight, this what my 7.5 footer looks like from the front.  Granted it sticks out a little further then a loader designed plow because its made for a truck.  It pushed 2 feet of snow pretty well (Ag tires) but I can see why others would go with a seven footer.  Also, do you have a garage?  This plow just barely fits through my door without angling it, your garage door size may be a consideration.
