About this trick
Split Bottom is a pretty common mount in a lot of old-school tricks.  Well, actually, it's common mount in a lot of frontstyle tricks, which sort of makes it common in old-school tricks.  It doesn't doesn't get used as much as it used to, for sure, but I'm sure there's still a lot of great tricks that are just waiting to be discovered.  Maybe you should be that explorer that reinvents frontstyle.
