I don't talk about your improving, mate, i thought you would that the video makers do comments on their videos to describe their boost/br strategies.
That's all
But if you want to do all the job, hey, that's fine
We just need that the fast guys are posting some new vids
PS : If i succeed a good lap (at least top 5) i'll post a new public video of metropia (i'm trying a new strategy on this track atm^^)... But it may be quite long
