Mike,
I ve sold 8 ft on L48s. A little heavier, but hydro. Here in NJ we don't get the size snowfalls you get. We've put 7 ft up to L4330HSTC which clears the tires when angled. Consider the size storms you'll be clearing when buying that blade. In significant snow falls the extra foot may hurt. Use the plow with a rear blade to ensure 1 pass cleaning.
