In many rivers, many people say chartreuse is the best color to use for corkie and/or yarn. But have lots of colors available.

When float fishing, for some reason, hot pink jigs are often considered the best. Avoid panfish jigs since the hook will be way too flimsy to hold a chum.

If foul-hooking too many fish, one thing to consider is dropping to a #1, or even #2 hook. And consider bending the hook point in a little bit.

A chartreuse/orange #10 spin-n-glow has worked great for me on one river...but the #10 corkie (reddish orange is my own current personal favorite on my favorite river, at least) + a bit of yarn is usually better, I feel.

Trying to avoid foul-hooking too terribly many chums is one of the biggest challenges in river fishing.
