For my r/d longbow, placing them at the fades signifantly quiets the bow. I can't imagine putting them at the tips. This would have to rob performance from the limb. But if you will notice....alot of people are making lots of money selling silencing material that robs performance(if you rob performance, the bow gets quieter...think about that....slow string = less noise...big puffy balls that are in no way aerodynamic, slow string=less noise...). I have tested most of the string silencers out there and the leeches are by far the worst for quieting the longbows and recurves I have tried them on. I will agree however that they do not rob performance because they are light weight and more aerodynamic than puffs or whiskers. Yarn puffs, 32 strands, no more than 2 1/4" diameter, between the bundles at 1/4 string length from where the string leaves the limb + limbsavers starting at the fades and moved tward the tips in 1/4" increments til the bow is at it's quietest, then pressed on firmly = the quietest I have ever been able to get a traditional bow! I have found, with this type of set-up, that once you get over 9gr/lb of arrow weight the bow doesn't get any quieter. That is to say that the bow is as quiet at 9gr/lb as it is at 12gr/lb. That is my 2 cents. If you don't believe me....try it for yourself, if it doesn't work, then I'll let you bash me about the head and neck at your favorite mall on Christmas eve.
