Easier to control the 2nd part from a backstoppie actually IMO, but I'll try that .
EDIT - Imposs to stoppie the top of that BB . You cant get a proper normal stoppie on the 2nd part either from grinding the 1st BB (only way across that part unless you jump the gap), so you should change it to BB grind to wheeli to krail to BB grind .
EDIT 2 - Just got close to the above challenge!
EDIT 3 - Again anyone?
EDIT 4 - Ok I've slid off it like 20 times now , but look at this, kinda did it, but owned it too .
