David These are fairly extreme. I'm sure the usual needle technique as you described works well in the hammers on the south side of note 50 ish but higher up this set seems like stone. I'll experiment on a few to see which way will work best. They aren't hung yet & I'm trying to salvage my investment. After doing some hammer sampling I'm installing a set of the PIano-tek supplied Abel Performance hammers on a BB Mason & for my money, As far as really dense hammers go, the needles still go in easily albeit firmly & doesn't have the essence of concrete. They are very heavy though. I suggested to Mark at P- Tek that they make a lighter version of this & he says it's in the works. Dale I would only use that in extreme situations with felt that has lost all tension from over heating or pressing and must simply be made less dense overall. The Renner blue, while it is generally harder than I prefer, is not that type of hammer and will respond to traditional needling procedures. I have voiced many new MHs and other manufacturers using RBs using this procedure that seemed like would not be able to be voiced down on first listening. Trust me, the hammers will respond. That being said, I do wish that the hammer manufacturers would figure out a way to dial in specifications on hammer density (or be more open buyer requests) so that they could really be custom ordered. The trend with both Abel and Renner is still too hard for most of my needs.
