Sound advice Alain. 3" does seem to be about the smallest size streamer that consistently moves & catches truly big trout (20"+). I too am a big fan of the Zoo Cougar & variations thereof, including jointed (sshhh, it's a secret....). Seems like different colors are hot on different days, and sometimes it changes as the day goes on. When a particular color is "hot", using it can be the difference between almost no fish and catching a lot of big ones. I used to think that color wasn't that important in streamers, but at moments it can be THE most important thing. I do agree that presentation is usually the #1 thing though, with color a close 2nd.
