Draw length..... Okay after doing some research i have a 30" length of pull. Measure tip of middle finger to other tip of middle finger (basically my wingspan) minus that number by 15, and divide that by 2 is how i reached my number.You need feathers, and your compound's arrows will most likely never work for the stickbow (way too stiff.)
What is the bow poundage and what is your draw length? I can get you pretty close to the right spine shaft with that info.
Place your nocking points with a bow square, usually ~ 3/8" or so above center.
It's alot to take in at first, but don't get overwhelmed and take it a step at a time. It'll all start to click. Tuning a stickbow sucks, but it's a necessary evil for something that's supposed to "simple" lol.
