Chuck are youcurrently using 20# power pro. If so, 20# power pro is the same diameter as 6# mono. Which is a little to small to be throwing on baitcasters. The general rule when going from mono to braided line is to match the line diameter of your old mono with the new braid. For instance I used to use 12# mono and when I bought my power pro I went to 50# which has the same diameter as the 12# mono. Not only is the bigger diameter line more forgiving on your baitcasters you can also see it much better when you are worm fishing, which makes detecting strikes much easier. I know you haven't broke off since you started using the polamar knot, but if you go to 30 - 50 # power pro I know you won't break off. I believe the Power pro to Monodiameter looks like this:
20# Power pro diameter = diameter of 6# mono
30# Power pro diameter = diameter of 8# mono
40# Power pro diameter = diameter of 10# mono
50# Power pro diameter = diameter of 12# mono

This is just a suggestion you might want to try the next time you respool your reels. Hope this helps. If you are using heavier than 20# power pro then disregard this post. The way I look at it is, you are not really gaining anything by using the 20# braided line. 20 # line just isn't thatheavy when you are fishing around weeds, pads, or any other kind of heavy cover. The object of braided lines are to give you the unbreakable power of 30 -50 pound test line in a small diameter. Just my .02. By the way great fish again my man!!!! Didn't mean to rant just wanted to share this info. It may help you out in the future. Then again you may think I am full of poopy.[8D]
