Charlie that looks great. I wish I could get one to turn out that nice. RxCuy,it is probably more important to state whether u are a split finger shooter or you shoot 3-under. IN GENERAL TERMS most 3-under guys,myself included find a nock height of 5/8 to be real close to perfect. For split shooters,that number is around the 1/2" mark. Get a bow square and adjust to where you need be based on your style. However if you are a 3-under guy....your gonna need a nock above. I use a single tie-on nock above my arrow. You can use 2 if you want. But YOU WILL need something above the arrow to keep things in line as Mr.Lamb stated. rat'
