Im sort of on the fence with this one. I feel that if you are fishing very spooky trout in frog water, The light tippets definetly out fish mono leaders. Too many times have I switched to a small 3 # tippet after the morning bite has stopped and it has acounted for a couple more fish. Spooky smallies will also hit a light diameter flouro over mono. Other times I use a 65 # braid straight to a jig and the fish dont seem to care, even in the clearest of water. I think that flouro has its time and place. Just not all the time. Good debate guys
