Lose leaf tea is much better anyway. You can get multiple infusions out of it which is nice if you don't need the caffeine the second time around (it's quite water soluble and mostly all goes in the first infusion).
A second infusion with bags always just ends up kinda watery and sad. Something about the leaves being smaller...
Look up "gongfu steeping", it is a well established method, e.g. "15 to 30 seconds for the first infusion, then add 10 seconds to each subsequent infusion. If it seems a bit weak, leave it for longer."
