Ron N </BLOCKQUOTE>          Ron         No. Renners and Abels are an untenable match in the pianos I put boards in.  I've had similar results as you in that the  Ronsen and Isaac hammers are very close to where I want them. (Stwy hammers are another story but I like them.) I do less to the Ronsen than the Isaacs. A like a bit of juice in the bass for bite and some of the last octave of treble hammers.    As I've said before I used to sell the Issac hammer and have hung and juiced/voiced dozens of sets. It's a great hammer for Masons,Kawais,Yamaha. I'm not as crazy about them in stnwys in general but have several sets that are the best I've ever heard. The wear factors are amazing.     My point was consistency of his product and how there treated during manufacture. On many occasions I use to pre juice hammers I sold when I could tell they were to soft. I sent them out and didn't get complaints, but I knew the product. I'd always get complaints about too soft a set and I hated it.      Does that cover it?>>Dale </HTML>
