Kangaroo - Curve Pull (Jambox surface)

Hello everyone!

I'm new to grasshopper and I'm having some troubles trying to create a surface similar to the jambox one...

I've been using the Kangaroo Curve Pull, but I don't know how to adjust the springs and the pull strenght properly, but I'm pretty sure that's a way of doing it...

Anyway, I'm uploading my files so you guys can take a look and I'm also accepting suggestions! :)

Thank you very much!
