In my experience the game can behave unpredictably, and you can try a stunt 1,000 times and get 90ft, then one attempt will get you 130ft for whatever reason. And naturally that'll be the one attempt you'll save a replay of, in the hope that you can determine what you did differently from the other 1,000 attempts. Besides the fact, why would someone show modded bails?
Some loverly spots. I missed that Freeway one in Los Santos - sweet spot.
