Rodney is the king of tech, no question. Yeah, he invented the flat-ground ollie, which arguably the most influential (and fundamental) trick ever invented, BUT, Natas and Gonz may also hold part of the crown. When Rodney started doing all that shit, it was in the "freestyle" skating context. Natas and Gonz were the first ones to take Rodney's discoveries and apply to the to the street.
I remember the first time I saw a heel flip... Natas did it in an Oceanside sreet contest from 1986. He didn't land it along with many other things he tried, lol, but he got close enough that I knew what to do. Later that day, I was outside learning it. The footage is below:

I also remember when Gonz did a backwards 50/50 down a handrail at a Savannah Slamma contest. The rail wasn't even technically part of the course, but he made it so... that's a street skater.
