I haven't thrown the Wrecker, but the Rising Star is definitely going to be earlier in the mids whereas the Wrecker is cleaner and will go longer before making the turn.
When I had the Rising Star, I was really surprised on the fact that I could actually use that ball on many medium patterns instead of the medium-light since the cover ended up being stronger than advertised. On medium-light, I noticed that the Rising Star would jump quickly when it hit friction, so that was a case of move left and wheel it. That was a good cover/core combo to say the least.
