This was just for myself but I think if it will help other people learn this trick I should share it with everyone. I based this off the way I did the hurricane topsoul compared to Aragon on the same obstacle.
Based on this new commercial
Hurricane topsoul left footed soul right foot leading
Start from further back than usual when spinning about a skate length away from the object in all directions. As I知 spinning throw the spin with my right arm but keep arm bent not extended as I'm spinning.
Left arm tucked and up so my thumb is above my head and my right arm is tucked into my side: at this point my skates are still touching the ground
At the point of my 180 I have jumped into the air my legs are still bent slightly
Turn and look down through the armpit of my left arm as I知 at alittle over 180 and I will see the obstacle I知 trying to grind. My knees will now be tucked as much as possible.
Keep rotating keeping your left arm high so it is now over your head and your right arm will be diagonally across from you to so you will not be off balance while spinning
Land in topsoul position with the back foot first then front upon contact my left arm will be slightly away from my head but still bent.
Now your left arm will move from further away from your head other arm will counter balance your left arm by being to the side but lower on the right side of your body
Now you should be in topsoul position bring your right arm forward and your left arm will move back until it is almost behind you
Now your right arm needs to counter balance your left arm by moving across the body and the left arm will be slightly bent and behind.
Balance the grind and land fakie
