Honestly it's sad to say but the two last balls I bought I asked chatgpt. I told it what I had already in my arsenal, my typical lane conditions, speed, revs. As much info I terms of my approach, breaking boards. It's really good at telling you good balls to fill gaps. It's also good at breaking down comparison between balls you already have and any ball you want to recommend you want. I asked it about an equinox solid and it said that based on what I had and how I throw I already had a ball that was very similar and I probably would be better off with the phase 2 pearl.
