It doesn't matter if the handle is glued on or a solid piece of wood. I like to add a leather backing to fill out the back of the handle on my bows for comfort. A few times I left a ring or two on the back of the handle instead of adding the leather. In both cases the extra wood seperated from the back. It will be a lot stronger if you have one continuous ring from tip to tip. You can add a leather or other flexable material to the back of the handle and get the same results without the worry of it popping off.
