JMHO /* > */ You Know?/* > */ Dale:/* With the usual block, be it 5 ply, 11 ply, or 342 ply, yes. With these hybrids, no, because the "tightness" is concentrated at the top of the block, and from there down, the fit is much looser than is typical. You wouldn't drill a Steinway, Bolduc, or multilam maple block at 0.266" for a 2/0 pin, would you? The result is that the tuner doesn't load residual torque into the pin that will screw up the tuning later. That's the main reason I had for trying a block like this. I find that 6.8mm leaves a very tight pin, that seems to stay tight year after year (so far), and feels *very* controllable in tuning, and is exceptionally stable. It takes some muscle, but it feels a lot like a good open face block to me. Ron N
