I knit both sleeves at the same time, instead of a Figure 8, its more of a schmoo shape (like a bowling pin) with a single twist of the cable between the sleeves (to cut down on spreading the stitch you end on and making ladders)
When I make my CPB I make it with 2 skeins at once, then as I knit one sleeve, I have the same amount of yarn for the other. If the strands get twisted, you just spin the ball.
following intricate patterns is easier. You do one row twice, then its done. you can even do color changes if you REALLY wanna go a bit Psychotic (just kidding)
you do have to keep track of the pattern AND the decreases (and color changes, patterns within patterns, etc.), but as soon as U can wrap your brain around the complexities, it is fun.
feel free to bug me if you have questions about how I do it, I M hooked on this way of doing my sweater sleeves (and socks, and sometimes multiple hats)
