Dark Matter   70x5.5x30
The Dark Matter does one thing really well - Big Backend Motion! This ball has to be the largest backend ball in the current lineup, and it could rival any symmetric ball on the market, currently. The Dark Matter is the new addition to the Tour Preferred Series lineup for 900 Global. With this variation of the S43 coverstock that is currently in the Boost series, the Dark Matter ends up with a beefed up cover that formulates to the S60 cover. This solid cover matched with the medium RG core gives you amazing length through the front part of the lane with a strong backend motion into the pocket. This is ideal for medium to dry lane conditions, and it could potentially take on a little more oil with some surface adjustments. I am not exaggerating when I say this may be the biggest backend ball on the market, and for a symmetric core, its even more impressive to have that much pop on the backend.    
      
All In   70x5.5x35
The All In is the newest addition to the Preferred Series line for 900 Global. This midlevel ball provides you a strong pearl cover with the S73 Pearl matched with the even rolling Clockwork core that has been in the All Day and All Night from last year's lineup. Overall, compared to those two respective balls, the All In is a stronger overall shape. With a 4000 finish, the All In will give you some good traction in the fresh oil, and the pearl cover will allow you to have that good backend motion that everyone wants to see. This is an ideal benchmark ball for me. It gives me a little surface to even out the fresh shot and get a good idea of what the pattern is doing, as well as a medium RG core that rolls in the midlane well. Overall, just not a  lot of overrreaction for this ball, and will be great to start out your league session with.
