Tawn, I am certainly no expert on mono, but I use 17 lb Stren MagnaThin on most of my spinning reels. If they even still make it, that's what I would recommend (it works for me). I forget what the true diameter corresponds to (maybe 12 lb test)?
I need to get more of this myself
I haven't bought any for a long time, I had a fairly large spool and I'm out
It's sensitive enough for perch/spot, yet handles summertime schoolie rock (livelining) with ease. With a good drag, you can even get a Skate to the boat close enough to cut the leader
For my TRUE spot rods, I use a lighter line
