In general, these days, as opposed to time when the Axure Pro Zone came out, balls are nowhere near as aggressive as these original Brunswick particles balls were. That is why it/they had such high RG values.
One of the few balls that fit in that old category are the Legend particle balls made by Lanemasters. Their particles are industrial diamonds. Balls like the Yeah Baby! (yes, unusual name) and the New Standard have fairly high RGs, but they, IN GENERAL, will hook more, not as early and be more flexible than the Azure was.
3 other balls that are very aggressive are the Brunswick Goliath, the LaneMasters Guaranteed and the brand new Visionary Centaur AMB particle and are balls fairly similar to your Azure when it was new. I strongly suspect they will be MUCH stronger than your Azure in its current very used condition. While it must still seem aggressive, it is probably much tamer than when it was new. So, no matter what ball you get to replace it, be careful abot your expectations.
