Landscapers use burlap, but spend time compacting the soil after they're wrapped to ensure the root ball stays intact. We used to tie the corners as tight as we could; pat the soil with our hands to compact it; then retie the burlap as tight as we could. For that size tree however it may be worthwhile to invest in a basket or 2, they could make your job a lot simpler.
As I'm sure you know, you'll want to dig the roots outside the drip line of the foliage; i.e, the radius of the root ball wants to be as big as that of the crown.
Good luck.
