If you want a serious reply...no bullshit, about 4 (or so) years ago for no other reason than purely nostalgia sake I gave Tracker trucks another look. It had been at least 15/20 years. Anyway, I skated both the Axis and the Dart (149) and I really don't have anything negative to say about either.
The Dart is more of a medium height, all around truck. Turning is fine, stable. The Axis felt a lot steeper and turned a lot quicker. I just thought both were a little on the heavier side so I went back to Thunder.
