Haven't even seen one in person, but anyone with a Lone Wolf stand definitely should use the Wolfjaws with the bow grommet if they plan on using the built in bow holder. By itself(bow holder with grommet), its virtually worthless.
My old PSE fits in the bowholder (with grommet)just fine without the Wolf Jaws. I think it's primarily the paralel/split limb bows that require the WJs.
