I've been running 15# and 20# PP on my float rods for going on two years now, and I love it. As mentioned, it floats, so very easy to mend. No stretch, so easy to set into a fish.

Downside: For whatever reason, this stuff will often roll off the top of the spool when the bail flips, so I have to watch for that. It also will tip-wrap easily, so if you set the hook and miss a fish, watch out.

Question for the rest of you though: I've never had any problem with line twist, but then I've never used the PP for spinners. I normally pop on the mono spool for that. Does the PP get line twist from spinners?
