Not trying to turn into George Kollias but I am playing more double kick stuff and refining my technique more. In doing that, I realized I'm a pretty heavily heel down player and the Axis Longboards felt funky for anything but heel up. I also have very limited space on my drum platform, so the longboard pedals felt cramped, I was stepping on the middle or top 1/3rd the the pedal 99% of the time. Anyway picked these up. Exactly what I was after, chain drive, standard board, dead simple parts and single chain. So far I'm loving them.
