Yep, you are definitely right about it being frustrated. I fished a Tiger lake near me a couple years back and had a few follows but couldn't convert. It got worse. As I continued fishing along, I started seeing Tigers at about 6 consecutive spots that had trees in the water. I couldn't get any of those fish to even look at my baits. Just seemed that I was there at the wrong time I guess.

I'm sure Red will offer his take on the throwback baits too. I always try to have a second setup with a different type of fly than what I am using for those exact situations. However, I have had more luck using the same bait that the fish followed, just fished from a different angle. Not sure if its just been a strange coincidence or what. There have been quite a few times where I've had a fish follow and I've tried throwing the other bait a few times and don't get any action. As we start to leave the spot, I switch back to original and try to get one last cast off the back of the boat and the bait gets crushed. The main difference that I can see is that the bait was traveling on a completely different path. I swear these fish do everything in their power to drive us crazy. LOL
