Ninja Pearl SE is the compliment to the original Ninja SE as the lanes transition and breakdown. Look for the Ninja Pearl SE to be cleaner in the front of the lane, storing energy to create a pronounced motion off the friction at the breakpoint. The pearl F70 shell is going to handle most medium lane conditions, or medium heavy conditions as the lanes open up and transition. Start with the original Ninja SE and then finish them off with the Ninja Pearl SE.
