I think it is essential for people to understand their equipment as best they can andbe able to tune it on their own in order to get the best performance out of it, and to fix things when they go wrong with no pro shop close by. With that being said I am trying to take in as much as I can with articles and posts as far as tuning the bow and arrow flight (my two favorites are the tiller adjusting article by Arthurand how to tie in a D Loop by Greg) but i have not found what I want on one key step which is sight elevation setting. In a lot of the articles I read you take a arrow place it on the rest, then level it to set the nock, then use laser or some other means to find center shot on the rest and move it over and then finally paper tune making fine adjustments on the nock and rest; but how do I set my initial rest elevation to start everything off with. I don't think this would matter but I am using a whisker biscuit.
