Just two set up for me too. Most of the time, the tree is too low for the expected travel. By the time enough limbs have been removed to get a good working height, it doesn't worth it any more. Usually.
The first one was an oak in the midle of an horse's practice. So, jumping the limbs over the boards fence was nice. Avoiding to embed a lot a sticks in the softened ground too. The second was a spruce in a very bushy backyard, no landzone. I could have done a perfect one for a big Cupressus arizonica on top of a step bank, with snaky stairs and a stone retaining wall dropping to the street, but we didn't get the job.
