I do the same in warm water. 0-3X.
Trout usually 6-7X unless it is early in am or late in evening, then I go to 1-3X in case a monster brown hits.

I recently caught about a 12-14 inch brown in the Little Red that fought me tooth and nail. Took forever to land it. The very next cast I caught about 16-18 inch brown that I literally just pulled in...

Smallmouth bass and blue gill are the kings IMHO.

I doubt you could land a 4lb blue gill(if it existed). I've caught some ~2lb blue gill I swore were 5lb largemouth bass.
