I LOVE bamboo. But I also LOVE nickle plated (Addis and Options). But I also LOVE Inox. This could go on for hours…
Point is, like Becjo pointed out, different yarns work better on different needes. I loved Inox until I tried them with a wool/alpaca blend. Felt like I was trying to drag them over sand paper covered in glue! I’ve got it on bamboos now, and it’s much better. My Options came yesterday (woooo hooooo!!!), so I’ll be trying the blend on them at lunch, I’m sure that will be my favorite. But I HATE working with cotton on a nickle plate, toooooooo slippery, tooooooo many dropped stitches. Bamboo and Inox are much better for me with a cotton yarn.
However, I wouldn’t be concerned about the bamboo bending or breaking because you knit on the tight side. It’s pretty tough stuff.
Keep tying out new needle/yarn combos till you find your LOVE/HATE list!
