Addi Rockets are just plain faster. Rockets have:

• sharp tips of the Turbo Lace needles to easily scoop up stitches
• the slick nickel-plated surface of the original Turbos so the stitches slide easily along the tips
• pliable blue cable
• US and metric sizes stamped on the cable
• lightweight hollow brass tips under the nickel plating

The 24" length is commonly used for knitting socks on two circular needles and for knitting children's sweaters in the round.
