Gillchaser,
I fish small spoons quite a bit and only use nylon lines. If a spoon is run at proper speed it wobbles and will not twist line, if reeled too fast and spins it will twist line. Sometimes you are in a hurry to recast and wind too fast, so I always tie a Raven micro swivel about 2ft. above spoon. They come in 4 sizes, all are very small and I use them for most lures if line twist is a concern. Hope this helps some.
