I used to swear by power pro, until it failed and they refused to stand behind their product.
I wanted to sneak in a quick trip after work, stopped on my way to the marina and re-spooled 2 reels with 50lb PP. loaded the boat and went out fishing. First cast wit a 3oz sinker and the line broke, sinker landed in the boat. It was broken clean, not knot failure. I tied up a new rig and broke off again. This continued for the rest of the day.
I e-mailed customer service who responded the following day requesting a line sample and the original packaging. Good thing I threw the packaging in the trash can at the marina where I re-spooled.
I eplained the situation and offered a sample, the reciept, and a copy of my bank statement showing the charge, they refused and insisted on the original packaging.
That was the last time I used PP, it came off all my reels that day.
