You do hear all kinds of stories about braid on the net. And a lot of them aren't true!
Most people don't really understand braided line. They seem to think that they can use the same break strength with braid that they did with mono, then wonder why they're having problems. I've talked to a lot of guys that have told me they tried braid but couldn't get it to work right. Then I'd find out that they used to use 10 lb mono, so that's what they spooled their baitcaster up with! Gee, they couldn't understand that they were having issues with the line…
I used 65, 80 and 100 lb. PowerPro on muskies, and the 80 & 100 were used on my sucker rods, when I was dragging 12 – 18 inch live suckers on a harness for late fall muskies. 95% of my muskies were caught on 50 and 65 pound PowerPro and it worked just fine. I only went to the heavier line on the sucker rigs when I was breaking 65 lb. on the hookset. Other than that, I never saw a need to go that heavy. Although nowdays they're tossing 16 inch spinners with hubcap size blades and ONE pound soft plastic swimbaits!!! So if you're going to use lures like that, you'd need the super heavy braid.
But for 98% of the fishing you'll do, I would guess that 50 lb will be sufficient. But let us know how that 65 lb works.
