I just setup a home brewed system.

I all I have is 4mm spectra going through a 6mm? or clear plastic tube. The plastic makes a loop of around 2 inches wide. I never thought it would be easy as cake to get in and out. Well it is, and I absolutley love it. I will eventually take some close up pictures and post them. My system is also lighter than any dogbone. The only weight that is actually there is the plastic tube's weight and that is lighter than any handle or dog bone system.

Plus, its extremely cheap and affordable.
