In fact, the was no significant difference in friction. Thats been my experience as well. In fact fooling around with these magnets I can hold the whippen and the capstan apart through the UW/DW measurements and find really no friction change. Perhaps a gram when the Change in BW becomes great enough. > What was different was a couple of grams of BW, added by the taller > heel. How would the taller heel add a couple grams BW ?
