I would also go with the 926LE. I have 2 Arien's machines. One is the 8526LE which has the 23.5" intake chute which is much taller than the chute height of the 7524 compact series.
When going up hill, you probably will have to lock both wheels to get the traction you need, especially in a 12" storm and higher.
You bought yourself a quality machine.
