Thanks guys. I re-read my post and had to laugh a little bit. I may not even have answered it LOL. I don't expect folks to share their secrets on how to catch their biggest fish.

What you said was exactly what I meant to ask. I usually have the most success on fish that are about 13-20 feet down. I had heard that sometimes especially on sunny days that a big pre-spawn fish may rise higher in the afternoon in an effort to warm their body temps.

i have tried it for several hours a few times when I was catching the deeper fish but to no avail. Just wondered if you accomplished folks out there have had any success doing this?

Particularly for a chance at a trophy, do you think it is worth continuing to try or is it better to just search for larger marks on the graph and stick with the depth ranges where the fish are active? Maybe I should try more subtle and natural looking baits up that high?

Tight lines!
