I tried to like fluoro (tatsu), but it just didn't work out. I just took it off one of my spools and replaced it with 15lb smackdown.

Braid is more sensitive than flouro when tension is on the line as there is no stretch.  Fluoro, being a solid line per se, could transmit more vibration or feel due to this characteristic but sensitivity and feel are all subjective, as can be seen by the varying responses.  You will hear a lot of slack line sensitivity for flouro but for me, I am not fishing slack at all so it is a non-issue.  There are so many factors in sensitivity and there is no quantifiable way to measure it so it boils down to you and your sensitivity on your rod and reel and skill.  Try them both and see what you like.  The rods i use flouro or a hybrid line on is not for sensitivity but more for the stretch and handling characteristics for the techniques i am fishing.

Well said flyfisher.

I bet your teaching your students with this amount of lucidity too..
