SBD strings are the best and they are on all my bows. They are the most perfect strings I ever had and if you give Pierre the proper dimensions of your bow, they fit like a glove. In fact they fit so precise, I don't need a stringkeeper anymore when the bow is unstrung.
The last long, don't show any creep, are deadly quiet and will make your bow faster. How much faster? I found out that yoy can count 1 fps for every strand less. So If you move over from 16 to 6 strands, you will gain 10 fps in speed. This is a rule of thumb ofcourse, it also depends of the poundage and type of your bow.
Putting a SBD string on your bow is like shooting with a new bow. At least 5 lbs more, you don't have to pull.
And as for Pierre: he is the finest gentlemen you will ever meet and a real pleasure to do business with. Great strings, great people and great service, who could ask for more?
