Let me clarify my experience with the stickiness. The dough itself in the bowl is very sticky, yes. But following UB's note to oil the hands and "heavily" flour the surface before flattening the dough, the naans before going on the tawa/skillet are not sticky at all. Rather they are mostly dry and very pliable.
My local BIR has a glass window that patrons can see into the tandoor area where the naan and tikka are made. When I see them preparing naan, they are very clearly as soft and pliable as UB's. The "throw between the hands technique" seems well-suited to a softer dough. In fact these are the only naans I've been able to really utilize that technique with. Most others are too hard in texture that I've resorted to rolling or pulling into shape.
From that perspective, I'd say these are quite BIR.
