Why are you using braid; distance or sensitivity? And are you using a spinning reel or a casting reel? And are you fishing from a boat or shore?
And you said you're considering a change. Why?
Spinning + distance: generally, a good match-up. Use the smallest diameter braid that will have 2x the test rating you think you'll need. The reason for the 2x is that the knot strength of braid is poor. Best to use bodied lines, like Fins Windtamer, to reduce wind knots.
Casting + distance: generally, a poor match, although I have heard of exceptions. The reason is that distance can be achieved, but by using somewhat smaller diameter braids. Those smaller diameter braids can dig in on a snag or hookset, causing a bird's-nest the next cast. This backlash, combined with the poor knot characteristics of braid and the higher velocities associated with distance casting can allow you to see one of the truly amazing sights in fishing: an expensive lure going "snap!" and traveling vast distances to exotic new places. Can you say, "Bye-bye"? ?????
If you're out for sensitivity, you're already aware by virtue of the PowerPro that you're using, that sensitivity is great. That's a characteristic that is pretty much equatable among all braids.
So ...... what are you seeking to improve? If it's noise, go to a round braid with high pic count. If it's twist reduction, get either a bodied line or else learn to tolerate a larger diameter line than what is "normally" advised. If it's abrasion resistance, I don't know what to tell you. New braids enter the marketplace every year. Maybe one is magically better, but I have no idea whether that's the case or which one it might be.
Naturally, these problems are exacerbated for shorecasters, because of our attempts to eke out just .... one .... more .... yard .... from the cast. If you fish from a boat, you're on Easy Street.
Good luck! jj
p.s. - if you're battling twist, remember that shorter rods (with fewer guides) can reduce twist by virtue of reduced friction.
