Dizzle,
There is NO WAY, that the GN will fit between the Cherry and SD! Depending on the layout, this ball would go between the SCB and the BCB or CB. My GN has a little more length in oil, BUT that just allows me to play the outside line. The particle cover alone will say that it cannot fit between the two reactive balls you suggest. The Cherry looks like it hooks more because of the snappiness, BUT the CB could not play the oil or carrydown that the GN can. The area that a GN owner needs to be concerned with is the layout of the ball in conjunction with the bowler's style. I may chamge mine from 4 1/4 x 3, with the pin at 1:30 to the ring. May lay it out with less length like 3x4. Will keep up with it.
