These are very different balls.  The original (I assume?) is a skid/flip ball made for medium (maybe a little less) oil while the X Factor Deuce is made for medium heavy oil.  42' is a very average length.  Which ball you want depends more on how much is applied, how clean the backends are, and your style.

Make sure you actually have a heavier pattern before buying an aggressive ball like the Deuce.  Many beginners confuse the ball hooking early and rolling out with a ball that doesn't hook much and with no power.
