I also spoke to a salesguy about this board, he says that it is the former X8, which I wasn't familiar with.
In addition he said that the flying V is a shallower V profile than the Sherlock so it's less squirrelly on hardpack/flats, a trait that I see in my Sherlock.
I don't think it can be exactly the X8. The Antler is directional and a few years later, and the marketing is pretty different. Unless it's just the X8.
