The Webster is the best stringer I have used. I have found that some bows have top limb tips that are not long enough to fit into the top cup of the stringer and still allow room for the bow string to slip into or out of the string groove in the limb tip. The best solution I have found for this is to cut a small piece of leather that has a small hole punched in a corner where a thin string is tied, with the other end of the string being tied near the top end of the stringer. When a top tip of a bow fits too deeply into the top cup of the stringer, push the little piece of leather into the cup to take up some room and decrease the depth of the cup. It is then an easy matter to pull the leather piece out using the attached string when you are finished stringing or unstringing that bow. Most of the time the stock stringer works fine, but not always. I have used little pieces of paper, cloth, string and other soft materials in place of the leather, but the leather seem to be the best solution. I would rather use the Webster than any other stringer for the reasons stated by others, but I do own and occasionally use other models, and they work fine too.
