I would like to save you guys a few dollars.
In the following photo you will find a slingshot made out of 2x4 boards.

The photo is from about 1995, when I first moved into my current house. The
boards were actually used for concrete forms. The sling part is made of
surgical tubing. The weight is a fishing weight, and the line is fishing line.
The fishing line is first unspooled and laid out on the tarp in front of the
sling.
This contraption would clear 140' tall Eucalyptus trees with ease. It would
shoot the weight much higher than the trees, but you don't want that. Any
light wind will blow your line away from the tree tops, so you aim just above
the trees. Over time I made several of these slings as needed. They are
just put together with wood screws.
My next experiment was a portable unit made out of 3/4" EMT conduit. Same
results as before, but not as sturdy. I would need to weigh the front to
prevent it from pulling up.

Just a warning on the surgical tubing - it will deteriorate over time.
