Sounds like your really chasing your tale. I see this so many times with people tuning, they are making adjustments that are counterproductive, or they are not interpreting the results correctly The fact that you shimed one cam is an indication this is happening. You need a total reset. Here is what I would do. First re shim the bow, top and bottom. Your shims should look like this ||○| on that right handed pse. Then re-install the cables, start with 5 twists in each. Then time the cams so they are hitting dead even. Put three twists in the string. Make sure bottomed the bow out and still timed perfect. Then Equally add or subtract twists from the both cables till your peak weight is about a pound over. At this point reset your rest. Start at 13/16. Tie a nock and d loop that is just hair higher then level. At that point your ready to start tuning. When your getting a clean bare shaft at 3 and 6 yards your there.
