Hi Dave. Had to smile when I read your question.
If you hit the 'search feature' you'll find this topic probably has more posts that almost any question you could ask.
Then add to the mix: 'to wax or not to wax' and you'll double the number of posts.:hehe:
In general, it's a good idea to apply tape, especially if you're doing 'dynamic casts' such as the snake roll, Circle, etc. These kinds of casts put a huge amount of 'tourqe' on the rod connections.
IMHO the best way to tape is to put a strip of tape 'up and down' the connection, then 'over wrap' this. But whether you do, or don't tape your connection points you should ALWAYS recheck same every so often. Even with tape, ferrules will loosen up over time.
Some rods manufactures more than others, polished connectors vs. 'sanded.'
