<HTML> <HEAD> <TITLE>Re: Renner hammers</TITLE> </HEAD> <BODY> <BLOCKQUOTE> Still some filing reduces the shoulder width & points up the strike point.  I'm concerned about the longevity & how many filings a tech could get should get from a set of hammers.  I usually figure one heavy filing & the hammers are done due to regulation requirements. Two light ones & your done. Know what I mean?   However when a hammer is showing this much true resilience, felt cutting by strings  is minimized & hammer life is extended considerably even in heavy use situations & Voicing stability also makes our lives easier & the tonal benefits are huge. </BLOCKQUOTE> My brother---I’ve been putting Renner sets on actions for a long time, and have many Renner sets in heavy use situations; because the felt is, as you say, good and resilient, I’ve had tremendous results vis a vis longevity and holding tone. You’ve assessed the situation correctly—the softer the Renner set, the better they are; this new AA Wurzen felt is ROCKIN’. David A. </BODY> </HTML>
