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.
