It has a 12 foot circumference, so that would mean what, a 6 foot diameter.

Actually 12 foot circumference equates to about four foot diameter--3.82 feet to be more precise. Divide circumference by 3 for an approximate measure (thus for your tree 12 divided by 3 = 4), or, divide circumference by 3.14 for a more accurate measure (for your tree 12 divided by 3.14 = 3.82).
Get a green log weight chart and work the numbers to see what weights you will be lifting. Look at crane weright charts and see exactly what they can do. Even at four foot diameter, a crane with a 2,100 pound capacity at that distance (you said about 105 feet for your tree) would be picking frisbee-like pieces.
I too would opt for the 60-70.
