How high do you guys run your seats? I see some people who have it pretty high, and others very low. Mines pretty medium, but a little high. I've been practicing barspins on the ground, and I can pinch my seat very well. I think that it is too low. Do I just need practice more, or should I move the seat up. If I do move the seat up, should I adjust the actual post, or just tilt the seat back a bit? I know it's personal preference, but just tell me what you do, and give me some suggestions. Thanks.
