Actually I don't think you can switch from trout to bass. I know you can't switch from bass to trout.
Don't forget to try some small to med hair bugs. They can be real killers. Top water for bass is great. I will say that I spend more time fishing gills than bass. They are so much fun. Carp, buffalo, and drum are my next targets. I am gearing up. I just have to find some.
