nah I dont hate on oldschool moves, it's just that the move doesn't appeal to me at all. I've never seen it used so it's probably some move to understand the basics of footwork, just like there is a 4 corner variation of toprocks, where you pretend that you're standing in a box and hit every corner. the move itself is barely used in toprock, but it's a good way to teach someone how to control your bodymovements during toprock.
oh and if you're actually serious bout learning new footwork techs, then you should buy "storm's footwork fundamentals", it teaches you lots of foundational footwork moves that are used by lots of bboys all over the world, either that or make up some techs of your own.
