RE: Tuning
It is not that easy, first you need to supply us with some stats, what bow, draw length (yours), is it cut to center, past. what arrows you are going to use.
Tuning itself is easy, get your initial set up, adjust race for optimum quietness, shooty you arrows to see grouping, field points and broaheads together. I bare shaft tuned once, will never do that again.
