<P>Bob M. at Pianotek thinks I need heavier hammers on this 9ft piano. The piano is generally in a studio and rolled out to a stage/gym a few times a year. I don't think I need a heavier hammer...</P>
<P>I mocked an Abel Standard hammer on key #33 with a stock weight of 9.1 grams gave me, with a 3/8" lead=11.5 grams on the key, a downweight of about 50 and a 25 gram upweight. The hammer was stock so it needs all the typical trimming which will lower it's weight and lower the downweight and upweight...a lower up weight is not good...</P>

<P>I have so many questions...is it so important to lower my R? On the sample the only really bad R was on #16 and #65...which raised my overall R...</P>
<P> </P>
<P>I haven't tried the shim to lower my R yet...</P>

<P>I really appreciate any input...</P>
