All three of these rods are supposed to be 13ft long. In slot 1 is the Sonik Dominator in slot 2 is the Sonik Insurgent and in slot 3 is the Sonik Gravity. As you can see, the Dominator comes up a little short. I don't think it has an effect on gameplay. But when you've been playing all day and night for days straight. You start noticing the little things.
I think the Sonik Vader XRS has the same issue when you put other 13ft next to it. Also not sure if Scent from Hell/Heaven are actually pop ups or not because description say they are but they are under the sink Category.
