You will have a lot of options for scenic/twisty riding if you enter Arizona on US60. If it is getting late, and you are ready for a break, spend the night in Springerville or Eagar. If you have an extra day, and want a real treat, head south on US191 to Alpine, AZ, where you can take US 180 back into NM to NM 78. Head west to US 191/Coronado Trail/US 666/ Devil's Highway. Head north for over 100 miles of the best, most scenic, twistiest road you are likely to find on God's green earth. If you don't have time for the Devil's highway, save that trip for another day.
From Springerville, I'ld take AZ 260 to Show Low, and then it is decision time again. US60 heads down the Salt River Canyon, and is another great ride that gets you to Phoenix and points towards the south. An equally scenic route is to stay on AZ 260 to Payson, then back to the north and the Mogollan Rim. AZ 260 goes left to Camp Verde and another great, scenic road. Stay on AZ 260 to Cottonwood and you can reach Sedona by heading north on AZ 89A. Go as far as you want up 89A into Oak Creek Canyon but you need to u-turn and head back south on 89A. More great roads back to Jerome and Prescott, then to Yarnell, and Yarnell Hill. By now, you may be ready for some non-twisty roads and that describes AZ 71 to link back up with US 60 and head west to California. Sorry for the long post, but you are in the middle of nirvana.
