U-Turn Particle is the strongest mid price Columbia 300 ball ever! This ball has the same core as the U-Turn coupled with our UFO (Ultimate Friction in Oil) particle to create more friction in the body of the oil pattern. This ball will slow down sooner before changing directions which will give you a smoother, more controlled reaction through the pin deck. It was designed for medium to heavy conditions and is a big star on the wet/dry conditions that are so popular today.
