Tried a pair of these out on my 2010 bone hunter they were pretty easy to install and looked pretty cool. After about 100 shots I noticed that the top one was hitting the string where it separates and attatches to the the top limb! I removed them right away. It is ashame because they really made the bow a little more quiet but it is not worth banging up my bow string. Just wondering if anyone else tried them and what you thought of them?
