The Apple was an excellent turnover!
I throw two shots that I call turnover shots. The one I use most is thrown flat to slightly anhyzer fairly low that will come back to the left. I throw this shot with Predators, Wraiths and Tee-Birds.
The second turnover is a shot that is released slightly hyzer to flat and turns right (RHBH) and holds the turn the entire flight. I throw a beat Tee-Bird, Cobra or Rhyno for this shot.
Regarding the second question, it depends on how far I need a disc to go to the right. For me, an anhyzer backhand travel further to the right than a forehand, and by extension, the forehand is more predictable a shot than the anhyzer backhand.
A backhand roller will go a long ways to the right but is very unpredictable for me.
