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.
Let me know how fast you are and which pyraminx you use in the comments below.
