811 is going to be stronger than the 2.0 and both are much stronger than either entry level balls. Unless you were to drill the 811 weaker, the 2.0 and 811 are essentially the same ball (type of reaction). They are both asymmetrical long and strong pieces to the point where the drilling and surfaces would have to be drastically different in order to see a huge difference. If you have the 811, i would drill it to be stronger and polish the 2.0 because it can handle more oil than the 2.0, whereas the 2.0 tends to be a bit squirty on heavier patterns.
As far as being, stronger than the freezes or cyclones,.... DEFINITELY!!! Basic law of bowling. Your asymmetrical equipment will be stronger because they have that something extra (flip block or core design) to get the ball to turn the corner. The entry symmetricals are cover dominant so you can manipulate the reaction with surface so long as you have friction on the back to get the ball to turn over. Hope it helps and good luck.
