Brickguy: So how did the X-Factor work for you. If the Trimax is good for light to Med Oil, wouldn't the X-factor be good for med oil because it pushes down the lane better and has more reaction on the back. That's what i heard from some people. Since the Vortex rolls early and sets up in the back, the X-factor would be good to go longer and have more movement on the back when there is more oil.
