BBP, I don't know the answer to your original question, but I'd sure like to know as I was considering those exact same two lines for a couple of my heavier duty spincast outfits. So if you get a "real" answer at some other site would you please post it here or send me an email as I'd really like to know. My intent for either line is for trophy sized fish that I don't want the line breaking to be a factor in losing them. If things work out how I'm hoping they will, I should be posting some mind blowing huge trout by next fall.
