Kaffe Fassett, who is the King of Intarsia knitting, recommends using long strands rather than bobbins and butterflies. The strands get tangled, but they are easier to pull out periodically than trying to keep the other options straightened out.
I've used the plastic bobbins, hand-wound little hanks, and left long strands. He's right. The long strands are easier to deal with than the others which tend to get caught on each other.
