BA, when it comes to shooting well, arrows are way more important than the bow, altho good arrows will not make up for poor or inconsistent form. The shaft is the heart and soul of the arrow. There is nothing you can do to a crappy shaft to make a good arrow out of it. It is great to make your own arrow, but be sure you start out with good matched shafts. There are a few suppliers on here who can provide them; I'm one and there are others, too.
Having the correct spine is important. Weight is too, but not nearly so much. Work with your supplier to get the right spine. The formulas usually work well, but test arrows will tell you for sure what spine you need. A five pound spine range, ie 55-59, is the standard. 55-60 is six pounds. With paper tuning, I can get a 3 pound range that will shoot bullet holes, beyond that I can start to see some tear. Fletching will make up for the pound or two, tho. If you want to talk about arrows, give me a call.
