It's kind of hard to explain but or example we know people like Lindsey Robertson, Neen Williams, and Luis Tolentino are all dedicated heelflippers. But what about the pros that seem to do both but have a better heelflip (or more comfortable looking heelflip):
Lewis Marnell always struck me as one of those people. He has a nice kickflip but it seems his heelflips were a tad bit better.
Jamie Tancowny, no doubt he has an amazing kickflip but his back heel from the emerica video and the heelflip he does over that bar are insane.
Vincent Alvarez, I don't see the dude do that many kickflip trick, but he seems fond of fakie heelflips.
Etc. Who strikes you as a dude who leans toward the heelflip side.
