General trap training may not be glorious in itself, but you have to walk before you can crawl. Building a complicated trap without the proper training simply isn't going to work.
There are many different styles of traps, all requiring their own skills and techniques. Without this generalized training, however, that specific trap knowledge won't do you much good.
