I have been struggling with the Pop Curve Force like so many other people have in the past. This will be something I will RFE. I hope SideFX can develop a better version of this tool.
I came up with a familiar idea to create my own custom curve force, and decided to share it with others.
Play around and let me know how I can improve it. It's early days and I hope to build on top of what I have.
Here is the file as well as an explanation video of how it works.
