I just put some on an old Bear recurve last night. A friend who uses them recommended 9" from the tip of the limb. I put them on because I have a little vibration that I can't seem to get out with string silencers and thought maybe it was the limbs doing the vibrating. My friend uses them as insurance in case a nock blows up so I figured that was a good second excuse. I haven't noticed much of a difference in the vibration so I guess it is the string after all. Although they are ugly, I plan on leaving them on since they are there.
