I have used pre-hung Steinway hammers about 3 times and they worked very well. The strike point was surprisingly close. It's common to have to move a few hammers when I hang them so moving a couple of theirs was no big deal. The reason I haven't used them more is simply that I'm not that fond of Steinway hammers. They can be made to sound good, but it seems I have to do a lot more to them than others. Renner will also prehang hammers if you send them samples but it seems like they charge $150.00 or so. For that price I'll hang them myself. Dave Porritt SMU - Dallas
