RE: Arrows...What do I need to do?
You can simply remove the rest and add the strike plate pad.You can order carbons with feathers. Start with 5" feathers with an off set/ left or right helical, it makes no difference. This will help stabilize the arrow flight better than a straight fletch.It doesn't matter which type arrow you use. Just as long as it is the proper spine weight and at least 9 grains per pound of draw weight. If you are shooting 47#'s then the total arrow weight should be 425grains. Check what your actual draw length is. If it is 29" then you should shoot 29 3/4" or 30" arrow. Which means you need to go up in spine weight.
How did it shoot after raising the brace height?
