I have a bow made from a Hill Half Breed blank, 68" a bit more whip ended than a normal Hill. I just got a string from Steve, aka Frankbullit, that makes this bow shoot softer and more quiet than any bow I have ever had the pleasure to own. The only thing is that I need to shoot five pound heavier spined arrows because of the increased performance. I think that the string has to do a lot with how quiet a bow puts out an arrow, I have often wondered if loop size comes into play as well. I have quieted down recurves by making strings with an extra long bleed outs and still keeping the loops as small as possible.
