I agree, I have read all 4 TBBs, but number 4 is the best one, it wouldn't hurt to skip ahead. And tempering is great, increases draw weight, or you can tiller back to the same weight and still have faster arrow speeds, and you can add deflex. The process of tempering is basically blackening the belly of the bow with a head gun or torch, while held in a form to deflex the bow. But there are some important details, best read about it first. Good Luck, Kirk
