I've heard that new listings get better visibility. If I have new inventory for a current listing, should I add to the inventory of that listing keeping the all of the watchers, or is it better to let it sell out and relist the same item?

I have a bunch of holos from base set, jungle, and fossil including a few base set unlimited charizards, shadowless Blastoise and Venusaur etc. With everything booming these seem to really be lagging. I'm considering selling or trading for some sealed, thoughts?
