Do you have the rest center tuned? If you do then it has to be the arrows are weak, or torque on the bow handle. If you are kind of new to shooting i would go with the latter. Turn the draw weight down, this should fix the tear. Start with one turn on each limb and go from there. If solo cam bows have to be timed what is the advantage? Just wondering because you are not getting good nock travel. All bow problems(including brand, Hehe) should be fixed before you try to tune. Try the limb bolt adjustments they should fix the tear.
