I've been rolling with a 85°x2.5"x45° drilling. Not quite pin axis, but I found this layout to really smooth out the reaction, while still having some flare to the ball. I am rev dominate/high tracker, so everything was pretty much skid flip just to help get the ball down the lane, and I had alot of over/under reaction because of it. Since the change to the new layout, the reaction I am seeing is an easy roll through the front part of the lane, and a nice smooth continuous motion to the pocket. Same roll every time if I do my part.
