I've got power pro on all my rods and I've never had an issue with line twist on my spinning reels.

I started out running 20lbs(6lbs dia) and then switched to 30lbs(8lbs dia) because it has more body and is easier to deal with. Seems to tip wrap less.

I usually double uni knot a section of mono to the end. Its probably not necessary, but it makes me feel better having some low-vis line close to my offering. I've never had an issue with the uni knot connection failing.
