Dennis, My strike weight ratio data shows that for a given key ratio the Pre-84 supplied by Steinway yeilds the highest ratio and therefore the lowest leverage. The Post-84 Hamburg Steinway parts yeild the lowest strike weight ratio and therefor yeild the highest leverage. The Renner USA falls somewhere in between. My advice is stay away from the pre-84 parts unless you have feather weight hammers. The Renner USA parts for medium weight hammer like Encore, Renner Blue. The Post-84 hamburg part for full modern weight hammers such as you get from Steinway. In all cases lets the key ratio be the quide. Acheiving a strike ratio that is compatable with the strikeWt is the ultimate goal. By the way, what's the price of NY shanks now? The population here on Martha's Vineyard goes from 11,000 in the winter to over 60,000 during the summer season. Needless to say I've got lots keep me busy. Bye Bye Stanwood
