5Shots guide is good , in it you will find a recomendation that your arrows are correctly spined for your bow before you start to try adjusting nocking point and centershot . This is very critical , if you are underspined you are going to get frustrated very quickly as nothing will work if the arrows you are trying to shoot are too weak for your bow . Auther gives good advise allso as 4 or 5 inch feathes stabilise your arrow quicker makeing broadhead tuning easyer for thouse who use enough stearing in the back of the arrow to control the stearing up front you have when you screw on broadheads . I missed your reply ,but am glad you solved the problem , good luck getting that big buck .
