Thats great to hear that you are doing so well with the Epons. I had the exact same experience a few years back after changing to Epon 503s after playing the Miura 501s for about two years.
Very recently, I built a new combo set of Epon AF Tours and 302s 4-5 and it is working quite nicely. Even though the short irons are blades, I still think they are more forgiving and pleasing to play than the miuras.
