Blake,
I am using a Montana. When last I checked the bow's speed was 192-3 fps. I was shooting Gold Tip carbon at 29 1/2 inches with 125 grain field tip and 50 grain insert. I don't know the total weight of the arrow. Also, if you want more speed switch to a Fast flight flemish string. I am using 12 strands.
I am now shooting Stika Spruce four fletch arrows from Northtwest Archery. They are spined for 60 to 65#.I can tell they are faster but not by much. They seem to shoot flatter. Most likely they are lighter.
HTH,
Martin
