I use a lot of Power Pro. I like it's small diameter and tight weave.
At the moment I have 6 or 7 spinning reels spooled with 10 or 20 pound red and 10 pound green.
I don't think I will ever put plastic line on a spinning reel again, just because of the line twist.
Buying a bulk spool and changing the line before each fishing day would be an answer, if I saw any advantage to plastic line...But I don't.
I found a bargain on 30 pound Fireline in 2005 and I'm still using it on a couple of casting reels. Spectra lines don't break down from ultra-violet rays the way plastic lines do.
Another reel has 30 Pound Power Pro, and two have the new Spiderwire Ultracast Invisi-braid...Which I won't buy again.
I have 80 pound Tuff-Line XP on two reels that were used for Pike, Musky and for pitching Jig and Pig down south.
Last Fall I received a free 300 yd. spool of 12 pound Trilene XL in the mail. I put some of it on a very small Calcutta and tried it for tiny crankbaits.
The line is okay, but as someone else mentioned, after using super-line for eight years, plastic lines feel dead and the amount of stretch is unnerving...I know Mono & Fluoro have there uses, water fleas etc, and it does make sense to put mono on most reels...
under the superline...so you can spool two reels from one package of the good stuff...HAHAHA.
Keven VanDam uses a lot of 17 and twenty pound Bass Pro XPS Fluorocarbon on his rods. Crankbaits with the lighter line go deeper than with the heavy stuff. Both sink, and he says they are low stretch etc. etc...
When I go south in October I intend to buy a spool or two and give it a try.
Even us old dogs can learn new tricks...grin.
Pure Fishing handles Trilene, Fireline, Spider Wire etc. If you have a problem with one of their brands contact them and they will replace the line. You mail them the spool and they mail back the new line.
