Somehow since the early 90's, vert seems to have left the difficulty of the lip and taken to the air. Maybe the mainstreaming of skateboarding and the television audience circus-like appeal of humans launching in the air played a part? Who knows, but take a look back to 1991
when Mike Frazier was doing half cab blunt backside 360 out on vert. Where are the new Mike Fraziers? I know the old one is probably holding cards and your money right now.
