Best Arrow set up: It is very easy to go down a rabbit hole when it comes to building an arrow for your bow, I know I’ve been down a few of them myself… So Before you get to crazy there is no perfect.. in physics/mechanics you always have to give up something to gain something else so there is only best for what I need.
What I’ve learned in my 30 + years of archery is the most important thing next to consistency is your starting point. What do I mean by starting point ? Keep in mind. Your bow, your arrow and its components is a system in which everything is connected and not independent of each other. Meaning when you adjust one parameter or change one component it has an effect on a different part of the system. Example you want high FOC so you load up the front of an arrow now your spine gets weakened.. So it is important to enter the system at a level that will yield the best results and since you can enter it at any point like buying a broadhead first and building around that. You need to pick a starting point. For most of us we are not going to have multiple bows for different situations nor do we all have the means to retune our bow for different set ups.
