Yeah, I can see why DV8 would be down towards the bottom. Their recent products just don't seem to have to popularity and/or staying power from other brands. I'm a big fan of the Grudge Hybrid and Diva XOXO, but both of those were from a couple years ago.
I think they might be painting themselves into too narrow of a corner. Many of their cores are pretty much the same... low RG, high differential, and asymmetrical. Not a ton of differentiation in ball motion given most of their coverstocks trend towards being on the strongest end too.
It's kind of nice if that's what you're looking for assuming you don't mind choosing from multiple options for the same result. Otherwise you need too look outside the brand for something else.
