Okay so after getting advice on the grainbill here is my complete recipe. Suggestions welcomed. 6.5gallon (low efficiency 60-65 predicted) 7lb pilsner 3.5lb white wheat 3.5lb flaked wheat .5 lb torrified wheat 1.5lb rice hulls single infusion, (system does not allow multi step) 154F. Because of this I added some white wheat although this is non traditional to avoid a stuck mash 15 ibu of saaz at 60 min, some bitter orange and coriander at end of boil
No type of malted or unmalted wheat is going to help avoid a stuck mash. But those rice hulls will. And you may want to use some yeast.
