Thanks, I did read from the beginning. The OLBA example was held to be bad as the suggested circle to land was not authorised in the circling restrictions. But, my point was, circle to land viz exist for a reason, and in the example given the circle to land viz precluded a circle to land. To answer the general case, one would need to compare the circle to land viz with the actual viz. If we are considering a case where they are equal or not limiting then the answer comes down to the points made, eg obtaining an amended clearance to break off from the missed approach. But, circling minima are higher in general than approach minima for obvious reasons, so its likely that in the general case of a marginal approach viz circling wouldn't be an option.
