RE: A Good CORDLESS fall away rest??
The only one I'm aware of is the FreeFall made by Montana Black Gold. I have the older version called a TrapDoor. It's been on four bows in 4 years and so far haven't had any problems with it mechanically. Guess that's why it keeps moving from bow to bow.
I've also used the Muzzy. Main reason? I hate cords and think these type of rests are way way overpriced considering it's many times just some sort of $20 prong rest with the spring reversed and a cord attached.
