Yes, the modded SR225s are heavy, more or less like the PS1. Not very comfortable. They need a reinforced and better padded headband, issue that I'm sure Picodeloro will adress in the near future.
The mod does not have a "name" still. Picodeloro is calling it SR225 HD (heavy duty), but I prefer PS225 (Picodeloro Series 225)

. The resulting sound is nothing short of astounding. A real eye (ear) opener. The sound profile is similar to the PS1, but with the differences due to the driver. The bass improves a lot, as well as soundstage and clarity, the last I think due in good part to the recabling.
This is not another "crazy mod". I think it may be The Mod for Grado lovers in the future. The only drawback is the cost. The mod needs specialized machinery and requires a lot of labor. I do not know if it can be made for a reasonable price. My guess is not, at least in the western countries

I will publish better pictures in a few days, but meanwhile here you have an advance:
