David Stanwood should be on your list of folks to talk to on this one. For my part a mid top is as heavy as I'll go and I almost never select more then top mediums. Leverage can be accomplished several ways and should be fairly carefully thought through. Moving things around and changing sizes of things like knuckles also affects speeds / power / and distance ratios of the parts involved and the action as a whole. So how much help ??? I havnt' done enough redesigning via Stanwood methodology to be certain of a good answer yet. Generally, I like to use the heaviest hammer the action as is will allow for whilst keeping me at or under Stanwoods recommended maximum front weights. I'm still not a fan of assist mechanisms when it comes right down to it. Mass / soundlevel conection as I worded it.... just claims that the bigger mass that hits the string the larger the sound created (all else being equal). Lots of arguments back and forth on this.... qualifications etc etc ad absurdum. My experience is tho that within reasonable limits... the basic postulate holds true.

Ok.. thats a statement as if of fact... and I know there are folks > who dispute the mass/soundlevel conection. But my experience is such. I would like to hear more about the mass/sound level connection. What would be the heaviest SW you've ever gone with? (Yeah, I know it has to work with the rest of the action geometry.) I can't remember from the last time I was testing parts on a D. How much help (or not) was a bigger knuckle? Barbara
