I have bass come up to the fly and do what looks like mouth the tail end of the bait and then fade off. The faster I strip the more aggressive the strike but it reduces the amount of fish that will come up and investigate. Last night I had over 30 fish swim right up to the fly then fade off about half took shots at the fly. I went 5/8 (3 came unbuttoned)on the bass but it was a little frustrating seeing what looked like the bigger fish show little interest when they got close. I'm thinking of going down in leader size but wanted to see if you guys had any ideas. It happens with all fly patterns.
