Read the article in TBM about catwhiskers... with a open mind! Don't believe everything you read, including me, try them for your self. Catwhiskers are the absolute best in string silencers in my opinion like mentioned above they never pick up burrs or weight from moisture and last till the sting needs replaced. You can trim them down to the size you need and you should because it takes very little silencer to work on a well tuned bow. If you do put them on full length sure they are over kill and heavy and will rob preformance. One normal length rubber catwhisker is enough to make atleast two maybe three silencers. What we don't know from the article is how they was installed, full length tied in a knot, served on full length or cut to length and put between strands and trimmed to the exact length needed. Although it was a pretty decent article and I enjoyed reading it I hate how some folks jump to a "scientfic" conclusion without the science and then it becomes fact from then on.
