PSE makes a fast flight bow but Iam not sure if this is the same one. You need to give the bow poundage and arrow length for the proper arrow size. Easton has a arrow chart at Javascript Easton Chart www.edersbow.com/catalog/easton_chart.htm. 4" fletchings seem to be prefered over 3" for hunting. Usually the smaller fletchings are used for lighter arrows for tournaments and 3D shoots. As far as the silencers. If the bow seems to be quiet enough with the spider legs than that should be fine. I just always used cat whiskers which work fine for me, but a lot of people like the sims vibration silencers for their bows.
