Extreme length and a big back end on what conditions? Light, medium, medium to heavy oil??? That might help people to decide whether to get one or not. Can we assume it's reactive, maybe even pearl? Not too many particles, even pearls, get the reaction you describe.
I can get the reaction you describe from a Power Groove Pearl, so based on your information alone, it wouldn't have a distinct reaction compared to any ball in my arsenal.
I know a little intrigue can be a good thing, but it could be an expensive mistake.
