The answer to your last question is that Blair (the owner) does not work that way! He will NOT sell you something he feels you don't need! And I guarantee you there are people shooting your exact bow, that have no buzz or any other issues! And I know people (like Chuck from Feather Visions) that had to add a vibe dampener to his so his elbow wouldn't hurt after shooting! It all depends on how the bow is set up and the bow itself! Blair would rather you experiment with it and possibly not need anything else, at an extra cost! If you do end up needing something, Blair has them or he will tell you where to get them!
As for the comment from the other poster about B-Stinger eventually adding some form of rubber or other flexible material between the bar and the weight, well I talked to Blair personally enough to say, without putting words in his mouth, that unless some new alien material is discovered, that maintains the exact amount of rigidity and still absorbs more vibration, that ain't gonna happen!! B-Stinger equals, a STIFF, RIGID, SOLID connection to the bow with NO flex anywhere!!! Sorry Blair if you have found said Alien material and plan to use it!!!:mg:
