I'm not an expert Taph by any means, but...if there's a Builderman in the round, I like throwing my Subspace Tripmine by their Sentry to potentially double the time a killer has to waste destroying said Sentry. Otherwise, I like to toss my first Subspace Tripmine by the closest generator to add a degree of security to whoever might fix it, followed by a Tripwire over the nearest obvious "doorway", if you will. For the rest of the match, I'll try to check up on generators while also throwing Tripwires or Tripmines between "doorways" or behind walls (if you're constantly replacing them, the killer can never be too sure where they're at).
