sounds like your just spinning off axis. when your comming into the jump get lower and lean into it a bit as you come off the lip. hopefully that will level you out in the air. i cant pull 7's so this might not be the best help
dude how so? jiberish beanie equivalent to the biggie talls = 22.95 and try scrolling down the jibij hat section, you dont see anything priced below $17 unless its echeadwear or on sale
you could wax it up, then it wont rust but yeah youd probably get more slideage on the metal then on the plastic. but if you slide like mad anyway whats the difference?
