So I'm looking at PowerPro for backing since it has been suggested here a few times. I see on their website a product called PowerPro Superline (goes for about $15/150 yds of 40#).

Am I looking at the right stuff and how does it compare in diameter to gel-spun (like Orvis Hi-capacity or Micronite)? I'm looking for higher capacity to allow me to downsize the reel.

Always appreciate the input. Randy
