Re: It's Another Opin 10 wt TCR Yes it's pricey BUT
You make a very good point of matching the line to the rod. This is especially true with the fast action rods. I have a 9'6" 5wt sage that I bought and was so disappointed in its performance. I tried a SA GPX line and it made it into my favorite rod. Just that 1/2 line extra weight was all it needed.
Where can I see that Berkley study?
