You might want to talk to Wally Brooks about this. There is a lot of 
differences is the weight of hammers. Did you by any chance keep the old 
hammers and shanks? If you did, weigh some of them, and then weigh the new 
ones. According to Wally, one once of hammer weight adds about 6 ounces to 
downweight, or visa a versa. If you didn't keep the old set, you might want 
to take weight off the hammer and shank, and see if that reduces the 
downweight.
