depends on how you define strong. if you define it as oil handling capability, then no, the pearl shouldn't be stronger, if you describe it as, how deep you have to play on a house shot, then maybe yes. for instance, if a ball starts midlane and keeps going (solid style), you may have to move everything right to create the right type of angle to carry. if a ball goes long and makes a strong, sudden, sharp angular move to the pocket, you maybe have to move way left and get it out right to create the right angle. either way you look at it, whether it is "stronger" or not, i'm sure it'll be another excellent ball.
