They sound and look great, but at that price point, I just don't know how much market share they will get. There are loads of other options out there in those sizes, and all of those options are significantly cheaper. Let's face it: most drummers aren't going to use a kit in those sizes as their main kit; it will most likely be a secondary kit or "fun" kit for almost everyone, and that's A LOT to spend on a secondary kit. Plus they are not even all Maple. They are maple/poplar.
It's funny, in that video, Mark Guliana (whom I really respect) says he loves the direct to shell mount and experiences no negative effects from it. Um, on a small 7" x 10"? I think if he took it off the mount, suspended it from the hoop by his fingers and hit it again, he might change his mind! Especially with that large Gretsch diamond bracket that literally takes up the entire depth of that shallow shell.
Having said all of that, that snare sounds absolutely golden when in the "high tuning" segment. They mic'ed and mixed that thing perfectly. Plus Mark Guliana could make a crappy Excel kit sound great.
