I knitted some socks from my husband last summer from bamboo yarn such as you describe. The yarn was soft, very nice to work with and appears to be very strong. I think you've made a good choice! The only problem I noticed with it was that the yardage on the ball was rather sparse. So, in using two balls of the yarn, I really didn't have enough to finish both socks. And my local yarn shop - from whence I had purchased it - didn't have any more in black, which was the color I was using. But, they did have purple, so what I did was to start both socks in the black that I had and knitted them to about the middle of the foot - and finished both in purple bamboo yarn that I bought to supplement my black. So, now my husband has a pair of black bamboo socks - with purple toes! It's our little joke!
