I do this and think it sometime helps but wondered about others doing it as well.

I have a 8wt Fly rod and reel and sometimes add a 9 wt line to the rod to cast better, basically adding an extra weight line. Do you do this? Do you add a higher weight reel, or just add 1 wt class higher line on that reel?

Example:
8wt rod with 8wt reel with 9wt line or
8wt rod with 9wt Reel with 9 wt line

Thanks and always looking to learn more from others
