Just use google and type in questions and keywords....... This stuff can seem very technical, but once you understand it, it's relatively simple stuff....... Also google up OL Adcock and go to his website and click on the link for bow tuning.... It explains alot.....


As for spine..... The "good ol' boy" definition is: Spine is a term used to define the stiffness of an arrow..... When shot, an arrow bends back and forth from left to right... Given the same arrow, a heavy bow will have more left and right motion than a light bow.... Therefore, a heavier poundage bow requires a stiffer spined arrow..... Now, some egg head has figured out a chart for the spine needed for any given bow weight and draw length..... The chart can get you pretty close but you typically have to do some tweaking with either the bow or the arrow..... Check out O.L.'s website, it can help....
