Been thinking about this particular action configuration a bit and have a few questions swimming around in my mind. Configuring an action such that it has heavy hammers with a high ratio is going to cause the need for lots of counterbalancing... and quite often ends up being in the form of strong somewhat randomly regulated assist springs. This combination of high ratio, high hammermass, and low key mass has on the surface of it a couple interesting features. Its essentially the only way you can achieve high top action inertia against low key inertia while providing high hammer acceleration for key acceleration.... which further expands the ratio of hammer for key inertia. It would also seem to provide for the greatest change in required finger force (ie <<heaviness>>) from ppp to fff play.... and perhaps thats not such a bad thing ???? Assuming one took the time to do a bang up job of evening out strike weights and key leading... and real even assist spring adjustments.... what are the downsides of this setup ?
