One other thing is the string, I might have missed but it should not be weighted down with heavy silencers, etc., and depending on material might be 8-10 strands, 12 max. for your weight. The string height should be as low as possible to gain speed, and still get good arrow clearance and flight.

My current string seems to be thick.It is what came with the bow.I'm hoping the SBD string(8 strand)will increase my speedat least to the low 160's.170 would be better because that is what my eyes and mind are used to but any increase would be good.I love the quietness of this bow compared to my BW recurve and will continue to hunt with it no matter the speed.After killing that spike with it,I'm pumped.It was almost silent on release and the deer never knew what hit him.He ran 60 yards and piled up.
