You shouldn't have your highbacks in the front holes. They need to be back against the heel loop. You're probably losing all of your heelside leverage because clearly your boot is too far forward in the binding and over the board.
Yes, I noticed that as well.
Cyfer: It looks like you messed up when rotating the highbacks. Not uncommon with Rome, because the rotation is a combination of changing holes on the highback (inner holes) and the baseplate (outer holes). Definitely check the manual sheet on this to get it right.
