Anyone else here using Miller's Milling AP (H&R) ?

A few months ago I was at Costco and bought a bag of their AP flour.  It's from Miller's Milling Oakland and is their Hotel and Restaurant AP.   I wasn't expecting much but thought it might work better for waffles (assuming it would have less gluten than my home milled Hard Spring Wheat).    

Since I was experimenting with sourdough and expecting a failed loaf, I used this cheap flour instead of wasting my good wheat --- but to my great surprise, I got a terrific loaf of sourdough.  Since then I've been baking sourdough just about every day using this AP flour and I absolutely love the results I'm getting ... I went through a 25 pound bag and went back and bought another bag.

Curious if anyone else is using this flour and what their experience is with it?
