Hi, the stab on the valiant is not adjustable, so permanently fixing it is fine if you never plan to remove it again. Tapping the carbon rod to make it removable is a very simple task, so I would not glue it in. If there is any play between the carbon rods and stab tubes you can build up the rods with some CA. That results in a tight fit with no play, yet can be removed if the need ever arises.
