I too have some grand pianos that I service that are like you say pretty much out side . They are at Restaurants that are open to and right on the ocean . They have string covers and about 150 watts under them . I got on email reply off the list about recommending the full system out here . I don't think that will ever be needed here . It's just dry enough that in some cases  (areas & life styles ) it might be possible at times a piano would be too dry with a constant 25 watts and then as RH swings high leaving the piano to wet . If more than 50 watts is normal or some cases even 150 watts then where in the world would it be a good idea to use 25 or less constant ? Or maybe I'm wrong about this . It just doesn't make sense .</P> <P>Brett</P></TD></TR> <TR UNSELECTABLE="on" hb_tag="1"> <TD style="FONT-SIZE: 1pt" height=1 UNSELECTABLE="on"> <DIV id=hotbar_promo></DIV></TD></TR></TBODY></TABLE><BR>-- <P>___________________________________________________<BR><B>Play 100s of games for FREE!</B> <A href="http://games.mail.com/">http://games.mail.com</A> </P></BLOCKQUOTE></BODY></HTML>
