Steve,
Well, considering the difference between your general climate scenario and mine, these do what every other piano around here does, even with a PLSS. But, in my typical OCD for improving stuff (if possible or practical), I would characterize the low tenor to the break to be a bit weak and tubby. If a switch to type 0 wire is all it takes to improve this, that's a very easy fix. I see little reason to fiddle with the remainder of the scale (bass should improve quite a bit with Heller optimization) since it sounds otherwise quite good. The only reason for doing this is loose tuning pins and it will be going into an institutional environment, so they need to be tight. So I'm not wanting to go to lengths to reinvent the wheel if someone has already done this exact piano and achieved significant improvements.
Don Mannino...any comments? This is a 1981 piano.

Peter, I tune 11 of these pianos annually for a group of churches on the island. They are all KG-2 C,D,or E. I've always wondered if the letters at the end are different scale designations. For tuning purposes I've sampled each letter designation separately. If you or anyone knows, I'm curious.
Other than that, all of them in the environments that I'm tuning them in stay in tune with themselves and hold their pitch remarkably well year over year.

I routinely run my string scales through Paulello's Typogram to see what might be suggested in terms of hybrid stringing. I haven't put a Kawai though this process since I learned it, but a Yamaha G5 has been one that worked out well. Typically I will see some recommendations for XM wire somewhere in the treble, and maybe some Type 0 or Type 1 in the low tenor. If I'm going to consider changing wire sizes, I'll run my scale through Tremaine Parson's PScale. I wouldn't expect to change much on a Yamaha or Kawai, but maybe a good idea might show up.

Has anyone here restrung a Kawai KG-2 and made any alterations in the scaling? I'm thinking like changing low tenor wire to Paulello and/or perhaps a gauge or two change, etc. Nothing big because its already a pretty good piano. Obviously, bass strings will get redesigned and be more tailor made...
Just wondering 🤔 (and yes, I know that the printed scale on the bridge is metric).
