I have been playing the Ebonite red sparkle as my first finger tip ball and I have to say What a revelation, I never thought I could have a ball that moved to the pocket so well (I play up first arrow if there is oil, as a lefty) and the thing just moves back to the pocket and smashes the pins everywhere! I dont get the same reaction on dry lanes though, it doesn't want to move as much, I just move in an arrow to second or just inside second It is very forgiving and even on Brooklyn balls it finds a way to strike What a ball Ebonite!!
