Know your machine first then learn how it's cutter comp works. I agree with others that have posted advice to ease into cutter comp. Other variations not mentioned, are controllers that will and will not allow changes in Z depth while cutter comp is turned on. Most in my experience would prefer that cutter comp be turned off at any time that Z moves are executed.

The tear drop, approach and depart, will still work well, you just have to remember to offset the finish contour by the tool radius, before adding them.
