I had considered putting something = with some more “body” in the slots, and perhaps the protek grease = is the answer. I have spoken to Bob at Pianotek about this problem, and will again before = taking the next step. I’m not sure that I’ve given up on Tokiwa as = a result of this, but I’m gettin’ there. Other than this, I like the parts, = and love the eveness of touchweight that I was able to get on both pianos with the adjustable = helper springs. One piano – a Mason AA with Renner wips – went from = the mid 60’s (grams) to the upper 40’s in the middle after the switch over, and = I removed 6 lbs. of lead from the keys. The customer was beginning to have muscular problems that limited her practice time but can now play for hours = pain-free. The other set went on my own Steinway, and even without the springs I = got better touchweight & friction numbers than with the Renner parts. I = do have problems with checking on my piano that disappear when I swap out = samples with Renner wips, though. Although they appear identical in the important = aspects, I suspect that the Tokiwas are shortening the action spread just slightly, = but I haven’t checked it yet.
