Why don't you guys try something that has worked for me.The result was concluded after a lot of testing,trial and error.The chrono is accurate,and we use an Appel press.The results where consistant using my LX,and my buddies Q2,Hoyt Razortech,Renegade SBD,and a 03 SC Bowtech Patriot.First off,the Simms string leeches seem to work the best for being quite(our opinion).But the main reason for all this testing was speed,and what effect the string silencers had.If you only put ONE string leech at the TOP(above) your serving,you will lose no speed,and the quiteness of the bow is the same.Whereas if you put two string leeches(one top & bottom),you lose between 3-7 fps,with no change in the bows quiteness.Check it out,I hope it works for you!!...Bob
