A lot of good responses here.

I generally like mono, but prefer braid in a lot of situations with spinners. I like fishing a thin diameter braid (to me one of the advantages over 10-15 lb mono), so that I can flip spinners further and to also have the blade dig dipper.

I also like the feel of a spinner while using braid, although I guess you pick up the vibrations pretty well with mono too.

The thin diameter braid does seem to wrap a lot though, both on the spinner's shaft, especially in current, as well as around the rod tip. I guess a mono leader solves the shaft part at least.

I've been fishing the moss PP some...but in the thin diameter it's almost impossible to watch your line, which I kind of like doing while sweeping a spinner. Maybe I'll try the yellow PP, or some of the Fin XS in pink. Is that stuff ridiculously bright? I like being able to pick up my line visually on the water, but not sure about the super high vis stuff.

Also interesting that there are a lot of different schools of thought here on lines for spinners...probably more so than for most techniques.
