As someone who was skating big conical full OJs since 2009
They don't flip that well, my board flips all caddy wompus like orbiting around the mass of the wheel, back to closer to normal wheels now and it flips so fast and easy
Also i miss my old grindkings damnit they were so light had a great inverted kingpin. They had this cool coating too that took a good deal of time to come off.
