of course!

I only use Yellow PowerPro...because I can see it. I love it when it fades white becuase you can see it even better. Very important when catfishing...or at least it is to me.
The only time I use red line is when i'm sandbass fishing and don't have to worry about watching the line.
sandbass - red or any other color
crappie - yellow
catfish - yellow or green (easy to see)
