Here’s a little known fact about tight loops, often considered the Holy Grail of flycasting. A tight loop is the de facto fly line response to a mechanically sound casting stroke. That’s right. If you’ve got a sound casting stroke (and use it in the correct length), you’ll automatically produce a tight loop. On every cast. The physics of flycasting simply don’t allow it to be otherwise. In fact, not throwing a tight loop requires a conscious adjustment to the casting stroke.
So if you’re struggling to throw tight loops, or to throw them consistently, it’s likely that your casting stroke contains flaws. Since nothing will improve your fishing more than improving your casting, fixing a faulty stroke is an excellent idea. A good instructor can easily get you started on the right path. Practice will be essential too, but acquiring a good casting stroke isn’t as hard as most people think.
