I have to agree. I was originally skeptical about the cable to the top limb, however after a year and a half I have not ever snagged it. I actually end up snagging the other parts of my bow more often.

As for the operation of the Whammy and the LD, they don't operate the same. The whammy sort of cocks like a release when the bow is drawn. When the cable releases the release sort of "fires" where it drops then comes back up. The LD at rest is pulled down aganst the arrow shelf. At the draw, the cable goes slack and the rest rises due to spring pressure. When you release, the arrow has support during nearly the entire power stroke. At the last couple inches of arrow travel, basically just before the fletching gets there, the cable goes tight and pulls the rest down and out of the way.

The one thing I really like about the LD is that timing is essentially solved by the nature of how the rest operates. It is immune to cable stretching, which is often times a huge problem with conventional drop aways.
