If you want as much of the vibrational energy to go into the bridge/soundboard system (impedance and all), the ideally the pin should be buried as deeply as possible in the trunk of the bridge (not the cap). Energy does bleed off into the atmosphere from the tip of the pin, and more as the pin is extended. When someone gives me that half a million dollars to set up that research facility that I've been waiting for, I'll get right on it, but in the meantime, intuition if not hard science would lead me to think that system efficiency is the issue. This will probably not be a satisfactory answer to your question, but it's the best I can do for now. PR-J
