We find that above 1/2 medium SW for a 6.0 ratio your going to have the possibility for weight problems... Top Medium SW with 6.0 ratio puts you well above the FW ceiling. 41 BW would keep it at the ceiling but this is still not a good dynamic combination. David Love's advise is good except for the fact that there are already 17mm knuckles, although I would go a little below TopMedium SW with a 5.8 ratio. I personally would prefer a 5.5 ratio as found in Hamburg Steinways with TopMedium and 38 BW. Perhaps angling the capstan and bringing capstan contact point out towards the balance rail side of the heel would work to bring the ratio down to a desired level if you want. Or just "smooth down" the Strike Weight down to 1/2 medium and rebalance the keys.... Thanks Richard for your exemplary use of Strike Weight Zones in the conversation... Mark, just send 88 SW's and we'll have 88 ratio calcs... You can use the data to fix errant SW's which is the most important thing to do before you balance the keys...
