I think by the "kickflip wallenberg" statement he meant doing anything down it shows a lot of skill and intestinal fortitude. And I'd have to agree.
and I don't think I'd lump gerwer in with puleo and oyola, considering I don't remember the last time either of those dudes did gnar handrail front boards or kickflips down massive sets/gaps etc. Unless you've really widened your hatred to all "mid-late 20 year old white dudes who've been ripping on an am/pro level for a decade plus". In which case, is really lame.
