One Strand or Two

I double the strands of Bambu 12 in the warp, but do I want to double the strands of Bambu 12 for the weft?

The bottom half of the picture is the single strand, and the top is doubled. Well, I picked the double strands for a couple of reasons. 1. The redder caste to the overall weaving is more pleasing to me. 2. It will weave up twice as fast (grin)

Now I am on a roll.
