Easy bank system 🎱 The 2-1 system is one of the most reliable way to predict long-rail bank angles. When the object ball sits along a lane, you can use simple math to find your exact aiming point, for example: if the ball sits under the 3 track line, dividing by 2 gives 1.5, which becomes your aiming point on the rail. The key is consistent speed and no English. #8ball #8ballpool #billiards #billiard #trickshot #tutorial #9ball | Orodbilliards
