Default opinions on an antenna idea

Hi, I just read instructions on building a "helically wound" antenna
using a broom stick.
http://www.hard-core-dx.com/nordicdx.../bromstik.html

After reading this, I had an idea. I'm doing more google searches for
this type of configuration, but wanted to ask here as well to get some
opinions. What if I took two broom sticks, and wound each with about
68 feet of wire. Each stick making half of a dipole antenna. Then
attach 450 ohm ladder line (or 50 ohm coaxial). How would this behave
when connected to a tuner? Would it behave like a 136 foot dipole, or
would it behave like a shorter dipole?

Sounds a lot like the Slinky antenna,
From what I've heard, using 2 slinkies (one on each side) will make a
40-meter dipole, and 2 on each side makes a 75-meter dipole (or was that a
20 and 40)?? But they used bamboo fishing poles as support instead of
broomsticks.
