LH with arrows to the right generally mean they are stiff. Options include lowering string height and then gradually increasing to find the best height. Adding steel adapter to your point and using heavier point (start with 50, 100, 150 gr). See if there is any change. Use a lighter string, but not much, may 2 strands.
Not all bows of similar weight are going to shoot the same arrows. One might be center-shot and another built out 1/8"; the first will handle a stiffer arrow.
I prefer a leather strike plate, because I add a piece of vinyl electrical tape which is heavier than the normal black tape if I need to build it out. This works with a stiff arrow from a center-shot bow. At some point the arrows fly better, group better and that is my approach. The harder material does not wear as fast as a softer material. Due to the paradox, the arrow is going to bend in on release, then bend around the strike plate. It is almost impossible for the shaft to maintain contact with the strike plate if you are shooting with fingers. That is why a stiff arrow will kick out. Just one man's opinion.
