I'm not arguing the geometry point; there is every reason to believe you are right. But -- I used a 5 degree head for two decades, and then tried a 20 degree head and knew immediately I had found a new home. It felt right. There is one huge benefit to using a "super-short head and a super- high angle" and that is the leveraged weight at the end of the lever when tuning grands. A short head is lighter and can move from grand tuning pin to grand tuning pin with ease. The weight of a larger head, leveraged as it is when tuning grands and holding the lever from a ball end, just feels wrong, awkward, unwieldy, etc. The difference in weight between a short and long weight is very noticeable because the weight of the head and tip are leveraged when tuning grands and holding the weight in horizontal position so far away from the hand. Choose your poison. Kent
