If you are finding the u-shaped cable needle akward, I would highly suggest getting a wooden one, or use a dpn (a small size 8 dpn would work). I had tried a j-shaped, and one w/a small "hump", and didn't like either, but I got the swing of things using a dpn, now own a set of wooden, grooved cable needs, and enjoy cabling a lot!
