Never found that it makes much difference.

In winter I use 15 pound camelion High or low both main line and leader.

In low water I use 6"pink worms drifted and floated. Rags in bright colors and subtle ones and jigs, as well as a wide range of other things.

I really dont think gear matters a bit from big and bright to small and subtle. its all about presentation. And some techniques work better in some conditions.
