Any tips for a 900

bigger jump, harder spin. all I got to say.

for the 9 its really all about a big enough jump and winding up a little harder than the 720, the only difference is that you have to be comfortable landing big spins switch. as for the switch 5, I know this is contantly repeted on switch spins but its important, don't start spinning until your in the air, wind up and then start your rotation after you leave the lip, if you try to spin early then you'll catch your tips and it will hurt

take it one step at a time... dont just bust a 9 if you cant spot and land a good 7.

same with switch. the more you practice the better you get. start with switch ones, then switch 3.s and make sure you can land them and feel very comfortable. same with regular rotations.

just start the day out with like, 180, 180, 180, 180, the do 360, 360, 360, 360 ect untill you feel comfortable to move up the rotation to another degree.

yeah just set your spin a little harder than you do for a 7. think about the feeling of the last 90 of a 540 and take that feeling to the last 90 of your 9. spot the landing at 7 but dont open up your body, keep your knees bent, or keep grabbing if your grabbing, and keep spinning and spotting your landing. stomp that shit and hit the next jump switch baller

A 9 should feel very similar to a 7.  Think about it the exact same, obviously you need to set it a little harder, but other than that everything until the landing should be the same.  As you come around to 7 just twist the lower half of your body around and look back uphill. It's really just about commiting to that extra 180.  do some 5s, it should be the same idea.  a 5 should be like a 3 with a little 180 tagged on at the end.  a 9 is like a 7 with an extra 180

The biggest thing you wanna avoid is looking down landing switch or you'll do a bunch of unintentional hand drags
