I have a new mod showing up tomorrow or Monday. Please let it be tomorrow. Anyways, I thought my new mod deserved a new top. I'm leaning towards the vision eternity. Seems to be a good design best I can tell. What I'm wondering is the 2 post caps (whatever they are called) that hold the wire down, it seems to me they would come off easily with time wearing out and such. Anyone have this problem or am I just being paranoid? Also any other issues I should be wary of?
