thpg is definitely not perfect but like I said before you need to switch between sim and reg mode to make up for the problems sim mode has...It only takes a few seconds to switch to sim in the in game options tho, so no biggie...And dont forget to turn the speed up to 10 while in sim mod...Also when rolling in sim mode you need to press R1(ps3) to push for more speed..
So like if you want to do a flip trick into a grind then switch to reg and turn the speed down so when you grind its not to fast.
