It depends on what I am going after.
The last few years, my best luck has been on rosie reds.
I think the reason may be because they are "something different" from what the fish usually see.
They have been awesome for Rainbows, but Brown trout seem to prefer the regular fathead minnows.
Rosie reds, if they are small enough, do seem to get more attention from the perch.
Hope this helps,
Wiener
