Adding Colliders to each VectorLine Point3 Value

I have created a few different VectorLines using Vectrosity and I am trying to figure out the best/most efficient way to hover over a point3 on the line and have a pop-up show up.

I was able to display a pop-up when hovering over the VectorLine using the below code, but the BoxCollider appears to cover too much space (see included image):

Code (csharp):

1.  
2. lines[0].vectorObject.AddComponent("BoxCollider");
3. lines[0].vectorObject.AddComponent("LineHoverOver"); // where LineHoverOver is a script that produces a pop-up box on hovering
4. lines[0].vectorObject.collider.isTrigger = true;
5.  

Is it optimal to create a new GameObject at every linePoint (the line points I am using are in world space and not attached to a transform) and then assign a collider to that game object? If so, what scale should I make the gameObject if I use a line width of 2 in Vectrosity, so it only covers the exact point and maybe a 10% radius around the point?

Or has anyone run across a better solution?
