I've just started AG and after reading a bit decided to go BIAB for a little less equipment up front. I've been doing it a little bit modified though, since my 7.5 gallon kettle isn't quite large enough for a full 5.5 gallon BIAB batch.
So what I do is mash in the bag with 5.5 gallons (and the grain takes up the rest of the volume in the kettle.) After 60 mins I pull out the bag and dunk it in another bucket with 2.5 - gallons of water, then pour that water into the kettle as well.
My first 2 batches both produced over 85% efficiency. It would have been about 67% efficiency with the initial volume alone. The bag dunk got me another 18-20%. I am pretty happy with that, and it is really no trouble to do either.
