"Low tenor [on Baldwin] had big pitch swings with humidity changes, too." I wouldn't deny that. Before Steinwanization, CCM had these two Baldwin F's. I could always tell when the heating and cooling guys dropped the ball at CCM because that would be the only time these would go out of tune.

First few years are a bit tough, but after year 5 or so, ours didn't feel any different from the Steinways. I sort of had a different experience with stability. The pitch stayed really close, but unisons would go pretty quickly (see earlier thread about left string flat, right string sharp). Low tenor had big pitch swings with humidity changes, too. Not the same as the Steinways next door, which always sounded better because the unisons stayed much tighter. I've tuned some new Steinways and other makes that had the same piano roll before the pin moved symptom, too.

I know a guy who was a piano tech at a school in PA. Dad. He showed me once when visiting the enlarged tuning pin on an SD he installed after breaking off a pin that wouldn't turn. He drilled it out. Sometimes the Baldwin Concert Grand will start rolling across the stage before the pin will start turning, if it ever does. Some attribute the stability of the Baldwin to the downbearing. I think it has something to do with the pin block as well. A pain to get in tune, but it stays there if you do it right.
