PowerPro
I used PowerPro for about 3 season on 2 of my drop shot rigs. I didn't like it, because of the "noise" it makes when retrieving fish, especially powerful fish like big smallmouth bass.
Before using the PowerPro, I had been using Fireline and never experienced the same noise. Reason being is that PowerPro is a braid and Fireline is a fused line. They are both very strong. I changed to PowerPro believing that I needed the extra strength (10/2) for the bass we were targeting. Wrong! After switching back to Fireline (Crystal) in 6# test, for my main line, I experienced none of the noise and have never had the line fail me, even with 4 & 5 lb. smallies coming out of 35' of water. So I know it works.
Whichever line you choose, make sure to use a 4' fluorocarbon leader however. It's less visible and does have some stretch, which acts like a shock absorber. The abrasion resistance of fluorocarbon is far superior to monofilament as well. NOTE: You do not need to "set" the hook when drop shotting either. Mearly raise your rod tip a bit as you start to reel will do the trick. You'll nail 'em with no problems doing it this way. And your sensitivity to light bites will increase dramatically.
One final thought; try the Gamakatsu Drop Shot hook in size #2. Works just as well on crappie as it does on smallmouth bass. The reason this hook excels in this presentation is that the point of the hook is straight, not curved inward, like a beak. This forces the point deep into flesh as opposed to going in and coming back out again. Very important with papermouths.
