Love your participant photo!
Let’s see if you are doing Option 1 – Community Loaves Dinner Rolls then the flour is the same. If you are going to make the Perfect Loaf Sourdough Rolls – I’d recommend the Sequoia or even the Central Milling T70, Artisan Bakers Craft. That makes a very fine soft sourdough roll. Not whole grain but d’lish. So many flours to choose from. If memory served I used the Skagit 1109 last year, also a very nice choice.
