Nice job on not getting frustrated and thinking through the process. Seems like the arrow length and point weight combo are working. Fletch some up and have fun shooting and working on your form. As you get better, and it gets close to hunting season it would be worth checking again to make sure they length and point are still bare shafting straight. This will make sure your broadheads fly right. Your might lengthen your draw some, or change your release a bit which over time which could affect the tuning of the arrow.
