I guess it would be a WC Lifesaver. The only time I tasted a Ludens cough drop was when I was about 4 yrs old, so I can't recall what those taste like.
Back on topic, my first bottle of WC from VRenu was really good - strong enough, juicy and very cherry, but the 2nd 30ml bottle I ordered was weaker, so that's why I ordered the flavoring - so I could strengthen it.
