Ball with this layout is Columbia Full Swing. Polished to also assist with being able to keep it straighter through the heads, added length, and to keep reaction once transition happens. Used it in league, was able to start about 10, pretty straight, with smooth reaction, as night went on, was able to use it all 3 games, from about 12 - 5 with no over reaction on back. Shot 657 with an open each game, and those were when I "grabbed or hit it" at the bottom and went high with 4, 6 7 left as result. It did exactly what I wanted it to do for these conditions.
