For the most part, I have always finished off bimimi doubles with a series of alternating half hitches and this has worked well for me. From time to time though, I start to experiment with the pull through loop. By this, what I mean is I form a loop with another piece of braid which I then turn the last dozen or so turns over. I then thread it thorugh the loop and pull it back through. This is certainly a little fussier than half hitches but the finish looks so clean.
i was wondereing whether anyone has done any experimenting with the strength of this finish over half hitches?
