It's a killer corner no doubt, but if there is someone on the inside of you then it can't be that perfect a line really. The common line through there involves hitting the outside of the wall on the right hand side when you come round the corner, that's ok if there's no one else with you but if its a bit chaotic you need to start very wide before the turn then turn in early to nearly come up straight with the speed pad. If you misjudge it though you can end up facing the wrong way :paperbag:D
All the ramming isn't people being cheats, it's just the game messing with your mind, it's still annoying as he'll when it happens but after a while you don't blame who you're racing against just the lag.
