i honestly think we'll see Lakai go before Vox and Circa. Vox and Circa don't have as many heavy hitter pros on the team, therefore they have a much smaller over-head. These brands are also generally sold in shops that DON'T carry the big brands (Nike SB, Cons, Adidas, and even Vans). There are tons of places around the US(Florida is a big one) that Vox and Circa do great because there are so many small shops that only sell these brands, Fallen and maybe eS (RIP).
I hate to see some of the best companies going under because of the big guys at Nike buying the heart of skaters.
