I hope that's not true about the sustain. I just bought a 4000 for pluggin on the surf and so far its been good and smooth. the guy that sold it told me it was great for what I wanted it for, light, fast, strong, smooth and affordable. I also just ordered a thunnus 1200 to replace my baitrunner 3500, which I love but would like a little more upgrade in strength since I beat on that reel plenty. lookin for a low profile baitcaster now, any suggestions? price is not an issue.
