There are at least two different environments on the indies that call for two different wrestling styles: One for more kid/casual audiences; one for more adult/diehard audiences.
Most of us start in front of kid/casual audiences. And those are especially the situations where the old veteran advice is so useful.
One way to get noticed by WWE or other major companies today is to make a name for yourself on the indies, which means appealing to the adult/diehard audiences too, which means working at a level beyond the simple, effective style that makes only kids react. We may or may not like that more complex style, but that’s a reality and a challenge this generation of wrestlers are the first to have to face to this extent.
Our predecessors have important stories for us to listen to and learn from, but almost none of the veterans of the 1980s understand what it takes to get booked in a super indie. They teach lessons about how to make it in wrestling in the 80s. In some ways the small local indies are like wrestling in the 80s; in some ways WWE still is; so their advice applies. But AIW, Smash, AAW, Beyond, Evolve, CZW, PWG, etc.: those promotions are far removed from wrestling in the 80s. So much of the old advice, while useful and important, is insufficient.
