Pyraminx is one of my favorite WCA events.
About a year ago I got my first pyraminx which was the Moyu Magnetic Pyraminx. I immediately started practicing and now I average Sub-4 with Intuitive L4E. I used LBL until around 8 seconds before deciding to learn a more advanced method.
I recommend Intuitive L4E, don’t learn the algs. There are many videos and walkthrough solves on Youtube. DGCubes has some good ones.
Listen to Episode #28 for an in-depth look on Pyraminx!
